★：jar包下載下傳不了的話可能是鏡像裡沒有這個版本，換個低版本的就行
★：eclipse工程validating很慢，可以先關掉驗證（一般對項目沒什麼影響）
★：eclipse工程pom.xml檔案報錯 到倉庫 删除所有以.lastupdate結尾的檔案
★：maven下載下傳jar包慢
解決辦法就是到setting檔案中，配上<mirror>标簽的内容 -->
加在<mirrors>裡面
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
0：maven .setting檔案配置jdk版本
在你的maven/config/setting.xml檔案的<properties>屬性中加上這段代碼
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
1：項目建立
在 Package Explorer 空白處右鍵建立Maven Project
-
為你的web項目配置tomcat環境
在你的項目右鍵→Bulid Path→Add Libraries→server runtime→添加tomcat Eclipse+Maven 項目建立 Eclipse+Maven 項目建立 完成後如圖所示： Eclipse+Maven 項目建立 Eclipse+Maven 項目建立 3.更改Deployment Assembly設定
将圖中用不到的三個配置Remove掉 Eclipse+Maven 項目建立 4.修改Project Fact
Eclipse+Maven 項目建立 在pom.xml檔案中的bulid節點加上
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
然後對項目alt+F5 更新項目 Eclipse+Maven 項目建立 Eclipse+Maven 項目建立 -
建立web.xml檔案
注意！ 第一次建立出來的web.xml檔案還不是3.1 要删除然後再建立一次。 這估計是它的bug吧 Eclipse+Maven 項目建立 6.在pom檔案中添加依賴
①：配置<dependencies>标簽

7：建立ssm架構用到的配置檔案
7.1：建立log4j檔案。内容如下：
#USE THIS SETTING FOR OUTPUT MYBATIS`s SQL ON THE CONSOLElog4j.rootLogger=DEBUG, Console#Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%nlog4j.logger.java.sql.ResultSet=INFOlog4j.logger.org.apache=INFOlog4j.logger.java.sql.Connection=DEBUGlog4j.logger.java.sql.Statement=DEBUGlog4j.logger.java.sql.PreparedStatement=DEBUG7.2：在mybatis檔案夾下建立mybatis-config.xml 檔案，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

-
建立java檔案
8.1 目錄結構
Eclipse+Maven 項目建立 8.2 UserController
package com.ssm.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.ssm.model.User;
import com.ssm.service.UserService;
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/")
public ModelAndView getIndex(){
ModelAndView mav = new ModelAndView("index");
User user = userService.selectUserById(1);
mav.addObject("user", user);
return mav;
}
}
8.3 UserDao
package com.ssm.dao;
import com.ssm.model.User;
public interface UserDao {
public User selectUserById(Integer userId);
}
8.4 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.ssm.dao.UserDao">
<!--設定domain類和資料庫中表的字段一一對應，注意資料庫字段和domain類中的字段名稱不緻，此處一定要！-->
<resultMap id="BaseResultMap" type="com.ssm.model.User">
<id column="USER_ID" property="userId" jdbcType="INTEGER" />
<result column="USER_NAME" property="userName" jdbcType="CHAR" />
<result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" />

</resultMap>
<!-- 查詢單條記錄 -->
<select id="selectUserById" parameterType="int" resultMap="BaseResultMap">
SELECT * FROM t_user WHERE USER_ID = #{userId}
</select>
</mapper>
8.5 User.java
package com.ssm.model;
public class User {
private Integer userId;
private String userName;
private String userPassword;
private String userEmail;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPassword() {
return userPassword;
}
public void setUserPassword(String userPassword) {
this.userPassword = userPassword;
}
public String getUserEmail() {
return userEmail;
}
public void setUserEmail(String userEmail) {
this.userEmail = userEmail;
}
@Override
public String toString() {
return "User [userId=" + userId + ", userName=" + userName
+ ", userPassword=" + userPassword + ", userEmail=" + userEmail
+ "]";
}
}
8.6 UserService
package com.ssm.service;
import com.ssm.model.User;
import org.springframework.stereotype.Service;
public interface UserService {
User selectUserById(Integer userId);
}
8.7 UserServiceImpl
package com.ssm.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.ssm.dao.UserDao;
import com.ssm.model.User;
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;
public User selectUserById(Integer userId) {
return userDao.selectUserById(userId);
}
}
9：資料庫搭建
CREATE TABLE `t_user` (
`USER_ID` int(11) NOT NULL AUTO_INCREMENT,
`USER_NAME` char(30) NOT NULL,
`USER_PASSWORD` char(10) NOT NULL,
`USER_EMAIL` char(30) NOT NULL,
PRIMARY KEY (`USER_ID`),
KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (1, '謝彥傑', '12345678', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, 'eangie', '123', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, 'eangie', '123', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (4, 'eangie', '123', '[email protected]');
10.在src/main/webapp /view下建立index.jsp
<%@ 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>Insert title here</title>
</head>
<body>
<h2>Hello World!</h2>
${user.userId}<br>
${user.userName}<br>
${user.userPassword}
</body>
</html>

12.項目右鍵 runAs/run on Server
然後一直點下去就行 Eclipse+Maven 項目建立
