**Spring-boot热部署**  
**方式一springloader插件 ：**  
1.新建maven项目添加依赖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>
      <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
      </parent>
      <groupId>cn.zds</groupId>
      <artifactId>20-spring-boot-springloader</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      
      <properties>
      <java.version>1.7</java.version>
      <thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
      <thymeleaf-layout-dialect.version>2.0.4</thymeleaf-layout-dialect.version>
      </properties>
      
      <dependencies>
      	
        <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>
      
      
    	<build>
    		<plugins>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    				<dependencies>
    					<dependency>
    						<groupId>org.springframework</groupId>
    						<artifactId>springloaded</artifactId>
    						<version>1.2.5.RELEASE</version>
    					</dependency>
    				</dependencies>
    			</plugin>
    		</plugins>
    	</build>
    </project>

2.正常编写controller

package cn.zds.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class DemoController {
    	@RequestMapping("/test")
    	public String getHello(){
    		
    		System.out.println("hello...");
    		return "hello";
    	}
    }

3.正常编写启动类App.java

package cn.zds;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    @SpringBootApplication
    public class App {
    
    	public static void main(String[] args) {
    		SpringApplication.run(App.class, args);
    	}
    }

4.在项目下新建lib，粘贴Springload的jar包  
5.在启动类App.java右键run congigurations  
**输入命令-javaagent:.\\lib\\springloaded-1.2.5.RELEASE.jar -noverify**

***注意点1：这种方法能实时更新java代码，但是对前端页面信息不能更新***  
**方式二devtools工具（个人推荐）：**  
1.新建maven项目 配置pom.xml依赖

<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>1.5.10.RELEASE</version>
      </parent>
      <groupId>cn.zds</groupId>
      <artifactId>20-spring-boot-springloader</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      
      <properties>
      <java.version>1.7</java.version>
      <thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
      <thymeleaf-layout-dialect.version>2.0.4</thymeleaf-layout-dialect.version>
      </properties>
      
      <dependencies>
      	
        <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>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
             
            <optional>true</optional>
        </dependency>
      </dependencies>
      
      
    </project>

2.正常编写controller

3.正常编写启动类

4.正常运行启动类就行了  
5.项目结构：

**特点：前后端都能及时更改，这个工具是通过重新启动启动类实现的，个人比较推荐**
