1. 使用maven构建SpringBoot的名叫spring-boot-springloader2项目
2. pom.xml
<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>
<groupId>com.bjbs</groupId>
<artifactId>spring-boot-springloader2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.13.RELEASE</version>
</parent>
<!-- 修改jdk版本 -->
<properties>
<java.version>1.8</java.version>
<!-- 指定thymeleaf和thymeleaf-layout-dialect高版本可以防止html标签不规范报错 -->
<thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.0.4</thymeleaf-layout-dialect.version>
</properties>
<dependencies>
<!-- springBoot的启动器 -->
<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>
</dependencies>
</project>3. 添加springloader的jar包
4. 新建UserController.java
package com.bjbs.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class UserController {
@RequestMapping("/login")
public String login() {
System.out.println("user login...");
return "index";
}
}5. 新建App.java
package com.bjbs;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* springBoot启动类
* "-javaagent:.\lib\springloaded-1.2.5.RELEASE.jar -noverify"
*/
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}6. 在src/main/resources/templates下, 新建index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>主页</title>
</head>
<body>
<span th:text="主页面"></span>
</body>
</html>7. 启动方式
7.1. 在spring-boot-springloader2项目上右键——>Run As——>Run Configurations...
7.2. Main面板中, 一定是当前项目名称
7.3. Arguments面板中, VM arguments中输入-javaagent:.\lib\springloaded-1.2.5.RELEASE.jar -noverify命令, 点击Run按钮
8. 使用浏览器访问项目
9. 修改UserController.java, 输出中添加aaa, 没有重启, 重新访问项目
