前言

以下針對于Spring + SpringMVC + MyBatis（SSM）架構的整合，隻是個人簡單的了解介紹，簡單記錄提供參考

一、整合環境準備

1、環境注明

Eclipse、Maven 3.5.0、MySQL 8.0.18、JDK 1.8、Tomcat 8、Spring4X、MyBatis 3.4.5

2、建立資料庫和表結構語句

在MySQL中運作：

CREATE DATABASE innerssm;
USE innerssm;

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for user_t
-- ----------------------------
DROP TABLE IF EXISTS `user_t`;
CREATE TABLE `user_t`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(40) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `password` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `age` int(4) NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of user_t
-- ----------------------------
INSERT INTO `user_t` VALUES (1, '測試使用者', '123', 24);

SET FOREIGN_KEY_CHECKS = 1;
           

3、配置Maven pom.xml

建立Maven工程，具體建立Maven工程可以檢視其他部落客教程

pom.xml檔案中引入依賴：

二、SSM架構整合

1、Spring：Spring架構是一個開放源代碼的J2EE應用程式架構，是針對bean的生命周期進行管理的輕量級容器。提供了功能強大IOC、AOP及Web MVC等功能。Spring架構主要由七部分組成，分别是 Spring Core、 Spring AOP、 Spring ORM、 Spring DAO、Spring Context、 Spring Web和 Spring Web MVC。我們平時開發接觸最多的估計就是IOC容器，可裝載bean，另外Spring的AOP，事務管理等等都是我們經常用到的。Spring架構比較強大，并不能三言兩語來概括，具體深入學習大家可以自己去了解學習—Spring官網

2、SpringMVC：SpringMVC是在Spring架構内置的MVC的實作。應用于web層，相當于Controller，用來處理使用者請求。簡單了解就是使用者通過位址欄輸入如：http://網站域名/login。SpringMVC就會攔截到這個請求，并且調用Controller層中相應的方法，經過一系列的業務邏輯等操作（其中這些都不是SpringMVC的職責），最終把結果傳回給使用者，并且傳回相應的頁面。就是處理前後過程表現，友善前後端資料的傳輸。

3、MyBatis：MyBatis 是支援定制化 SQL、存儲過程以及進階映射的優秀的持久層架構。可以對配置和原生Map使用簡單的 XML 或注解，将接口和 Java 的 POJOs映射成資料庫中的記錄。個人通俗了解就是能自由控制SQL，提升資料庫通路的效率。可以使用 XML 的方式來組織管理我們的SQL，友善管理和後續優化。

1、SSM架構搭建配置

（1）Spring和MyBatis配置

在resources的資源檔案目錄管理XML配置檔案

建立applicationContext.xml的配置檔案，其中包括：

（1.1）Spring架構注解掃描配置；

（1.2）資料源c3p0連接配接池配置；

（1.3）Spring和MyBatis整合配置；

（1.4）事務管理配置；

編寫具體的配置資訊：

<?xml version="1.0" encoding="UTF-8"?>

	        <property name="maxPoolSize" value="5" />
	        <!-- 初始化連接配接池中的連接配接數，取值應在minPoolSize與maxPoolSize之間，預設為3-->
	        <property name="initialPoolSize" value="1" />
	        <!--當連接配接池中的連接配接耗盡的時候c3p0一次同時擷取的連接配接數。預設值: 3 -->
	        <property name="acquireIncrement" value="1" />
	    </bean>
	    
	    <!-- spring和MyBatis整合，不需要mybatis的配置映射檔案 -->

	        <property name="dataSource" ref="dataSource" />
	    </bean>
	    
	    <!-- 開啟注解事務管理器 -->
	    <tx:annotation-driven transaction-manager="transactionManager"/>
	    
</beans>
           

其中jdbc.properties資料源連結具體資訊配置：

#資料庫驅動
jdbc.driver=com.mysql.cj.jdbc.Driver
#資料庫連接配接
jdbc.url=jdbc:mysql://localhost:3306/innerssm?characterEncoding=utf8&amp&serverTimezone=UTC
#使用者名
jdbc.username=root
#使用者密碼
jdbc.password=123456

           

（2）SpringMVC配置

在resources的資源檔案目錄建立springMVC.xml的配置檔案，編寫配置檔案内容：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    	http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx.xsd">
		
		<!-- 自動掃描該包 @controller注解的類-->  
    	<context:component-scan base-package="com.sslt.controller"/>
    	<!-- 開啟springMVC的處理器映射器和處理器擴充卡的掃描 -->
    	<mvc:annotation-driven/>
    	<!-- 配置視圖解析器-->  
	    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
	        <property name="prefix" value="/WEB-INF/pages/" />  
	        <property name="suffix" value=".jsp" />  
	    </bean>
	    
	    <!-- 配置檔案上傳，如果沒有使用檔案上傳可以不用配置，當然如果不配，那麼配置檔案中也不必引入上傳元件包 -->
		<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
			<!-- 預設編碼 -->
			<property name="defaultEncoding" value="UTF-8" />
			<!-- 檔案大小最大值 -->
			<property name="maxUploadSize" value="10485760000" />
			<!-- 記憶體中的最大值 -->
			<property name="maxInMemorySize" value="40960" />
		</bean>
	    
</beans>
           

（2.1）在web.xml中配置DispatcherServlet前端控制器

<!--配置前端控制器 -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 加載SpringMVC的配置檔案 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springMVC.xml</param-value>
		</init-param>
		<!--啟動伺服器，建立該servlet -->
		<load-on-startup>1</load-on-startup>
		<async-supported>true</async-supported>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
           

（2.2）在web.xml中配置解決中文亂碼過濾器

<!--解決中文亂碼的過濾器-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>

        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
           

（2.3）在web.xml中配置ContextLoaderListener監聽器

Spring監聽器，預設隻加載WEB-INF目錄下的Spring核心配置檔案，為了友善配置檔案管理，我們自定義配置加載，友善維護和管理。

ContextLoaderListener監聽器配置：

<!-- Spring監聽器，預設隻加載WEB-INF目錄下的applicationContext.xml配置檔案 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
	<!--加載Spring核心配置檔案 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
           

（2.4）web.xml中配置的整體配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"

		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
	
	<!-- Spring監聽器，預設隻加載WEB-INF目錄下的applicationContext.xml配置檔案 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
	<!--加載Spring核心配置檔案 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	
	<!--解決中文亂碼的過濾器-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    <!--配置前端控制器 -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 加載SpringMVC的配置檔案 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springMVC.xml</param-value>
		</init-param>
		<!--啟動伺服器，建立該servlet -->
		<load-on-startup>1</load-on-startup>
		<async-supported>true</async-supported>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
</web-app>
           

2、日志配置檔案

在resources的資源檔案目錄建立log4j.properties配置檔案

log4j.properties具體配置資訊：

log4j.rootLogger=INFO,fileout,stdout

#如果有特殊的包需要不同于根日志級别，在此配置
log4j.logger.com.ielpm.pay.df.tfb = INFO

# 控制台輸出，上線時注釋該段落
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d (%F:%L) %-5p %c - %m%n

#檔案輸出
log4j.appender.fileout.File=${catalina.home}/logs/innersystem/innersystem.log
log4j.appender.fileout.ImmediateFlush = false
log4j.appender.fileout.layout=org.apache.log4j.PatternLayout
log4j.appender.fileout.layout.ConversionPattern=%d [%t] (%F:%L) %-5p %c - %m%n
#Buffer size 8K
log4j.appender.fileout.BufferSize=8192
log4j.appender.file.encoding=UTF-8



           

3、整合初始測試

（1）建立jsp頁面，并編寫controller代碼

在webapp下編寫index.jsp頁面

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>項目測試</title>
</head>
<body>
	<a href="user/test">初始測試</a>
</body>
</html>
           

在WEB-INF/pages下編寫user.jsp頁面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>測試</title>
</head>
<body>
	<h1>測試成功...</h1>
</body>
</html>
           

在controller層中編寫代碼UserController.java類

package com.sslt.controller;

import javax.servlet.http.HttpServletRequest;

import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping(value = "/user")
public class UserController {
	
	/**
	 * 日志對象
	 */
	private final static Logger logger = Logger.getLogger(UserController.class);
	
    @RequestMapping(value = "/test")
    public String Index(HttpServletRequest request, Model model){
    	System.out.println("請求成功......");
    	logger.info("日志列印......");
        return "user";
    }
    
}

4、Maven中使用MyBatis自動生成代碼

在pom.xml中添加：

<build>
		<plugins>
			<!-- Mybatis Generator 代碼自動生成插件 -->
			<plugin>
				<groupId>org.mybatis.generator</groupId>
				<artifactId>mybatis-generator-maven-plugin</artifactId>
				<version>1.3.5</version>
				<configuration>
					<configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
					<overwrite>true</overwrite>
					<verbose>true</verbose>
				</configuration>
			</plugin>
		</plugins>
	</build>
           

在resources的資源檔案目錄建立目錄generator和generatorConfig.xml配置檔案

generatorConfig.xml配置檔案具體内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

User.java

package com.sslt.entity;

public class User {
    private Integer id;

    private String username;

    private String password;

    private Integer age;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username == null ? null : username.trim();
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }
}
           

UserMapper.java

package com.sslt.mapper;

import com.sslt.entity.User;

public interface UserMapper {
    int deleteByPrimaryKey(Integer id);

    int insert(User record);

    int insertSelective(User record);

    User selectByPrimaryKey(Integer id);

    int updateByPrimaryKeySelective(User record);

    int updateByPrimaryKey(User record);
}
           

UserMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.sslt.mapper.UserMapper">

		where id = #{id,jdbcType=INTEGER}
	</update>
</mapper>
           

5、SSM架構整體測試

（1）業務邏輯層

建立接口UserService.java類

package com.sslt.service;

import com.sslt.entity.User;

public interface UserService {
	
	/**
	 * 使用者資訊查詢
	 * @param user
	 * @return
	 */
	public User selectParma(User user);
	
}

           

建立Service實作類UserServiceImpl.java，實作UserService.java的接口，注入資料通路層接口UserMapper

實作類UserServiceImpl.java

package com.sslt.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.sslt.entity.User;
import com.sslt.mapper.UserMapper;
import com.sslt.service.UserService;

@Service
public class UserServiceImpl implements UserService {
	
	@Autowired
	private UserMapper userMapper;

	/**
	 * 使用者資訊查詢
	 */
	public User selectParma(User user) {
		return userMapper.selectParma(user);
	}

}

           

（2）資料通路層

在UserMapper.java類中添加接口selectParma()

在UserMapper.xnl配置檔案中添加接口**selectParma()**實作方法

<select id="selectParma" parameterType="com.sslt.entity.User"resultMap="BaseResultMap">
		select
		<include refid="Base_Column_List" />
		from user_t
		where username = #{username,jdbcType=VARCHAR} and password = #{password,jdbcType=VARCHAR}
	</select>
           

（3）控制層

在controller中的UserController.java添加：

/**
     * 跳轉登入頁面
     * @param request
     * @param model
     * @return
     */
    @RequestMapping(value = "/login")
    public String login(HttpServletRequest request, Model model){
    	logger.info("跳轉登入頁面......");
    	return "login";
    }
    
    /**
     * 使用者登入處理
     * @param request
     * @param model
     * @return
     */
    @RequestMapping(value = "/userLogin")
    public String userLogin(HttpServletRequest request, Model model){
    	String view = "";
    	User user = new User();
    	user.setUsername(request.getParameter("username"));
    	user.setPassword(request.getParameter("password"));
    	logger.info("登入請求成功......");
    	User userParma = userService.selectParma(user);
    	if (userParma != null) {
    		model.addAttribute("user", userParma);
    		model.addAttribute("message", "登入成功");
    		view = "success";
    		logger.info("使用者登入成功資料：" + userParma);
		} else {
			model.addAttribute("message", "登入失敗");
			view = "error";
			logger.info("登入失敗......");
		}
    	return view;
    }
           

（4）視圖層

建立login.jsp

			<button type="submit" class="btn btn-primary ">登入</button>
		</form>
	</div>
</body>
</html>
           

建立成功頁面success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

			</div>
		</div>
	</div>
</body>
</html>
           

建立失敗頁面error.jsp
