接上一篇 SpringBoot学习05–使用MyBatis-Plus代码生成器，在其基础上整合
thymeleaf
。
1. 添加 thymeleaf
thymeleaf
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
完整的pom.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.6.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.example</groupId>
<artifactId>demo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>demo</name>
<description>Demo project for Spring Boot</description>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.1.2</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.1.2</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.10</version>
</dependency>
<!--mybatis-plus完成项目构建所需模板，真实项目不需要使用-->
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
2. application.yml
thymeleaf
application.yml
thymeleaf
完整的
application.yml
如下：
# datasource config
spring:
datasource:
url: jdbc:mysql://localhost:3306/demo?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
username: root
password: admin123
driver-class-name: com.mysql.cj.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
thymeleaf:
mode: HTML
encoding: UTF-8
prefix: classpath:/template/
suffix: .html
servlet:
content-type: text/html
cache: false
# mybatis config
mybatis-plus:
mapper-locations: classpath:mappers/*.xml
type-aliases-package: com.example.demo.model
global-config:
db-config:
id-type: auto
3. 在 resources目录下新建 template目录存放页面
如上图，在
template
下面新建一个
account.html
页面
account.html
内容如下：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
账号信息
<h3 th:text="${account.name}"></h3>
</body>
</html>
4. 添加 AccountController 代码
package com.example.demo.controller;
import com.example.demo.entity.Account;
import com.example.demo.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.stereotype.Controller;
/**
* <p>
* 前端控制器
* </p>
*
* @author zorroxu
* @since 2019-07-05
*/
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountService accountService;
@GetMapping("/{id}")
public String getAccount(@PathVariable("id") Long id, Model model){
Account account = accountService.getById(id);
model.addAttribute("account",account);
return "account";
}
}
5. 测试
DemoApplication.java
代码如下
package com.example.demo;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan(basePackages = "com.example.demo.dao")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
启动，可以看到控制台输出如下
从上面可以看出，Tomcat启动成功，端口使用的是默认的
8080
端口，如果想修改这个默认端口，可以在
application.yml
中添加如下信息：
server:
port: 9990 #这里改成9990，你可以改成自己想要的端口
现在来测试页面是否正确输出
在浏览器中输入
http://localhost:8080/account/1
，可以看到页面显示如下：
至此，整合完成。
