IntelliJ IDEA 2017版 springloaded实现热部署

1、配置pom.xml文档

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

     </properties>

     <dependencies>

             <artifactId>fastjson</artifactId>

             <version>1.2.15</version>

         </dependency>

         <!--&lt;!&ndash; spring boot devtools 依赖包. &ndash;&gt;-->

         <!--<dependency>-->

             <!--<groupId>org.springframework.boot</groupId>-->

             <!--<artifactId>spring-boot-devtools</artifactId>-->

             <!--<optional>true</optional>-->

     </dependencies>

     <!--构建节点-->

     <build>

         <plugins>

             <plugin>

                 <groupId>org.springframework.boot</groupId>

                 <artifactId>spring-boot-maven-plugin</artifactId>

                 <!--<configuration>-->

                     <!--&lt;!&ndash;fork :  如果没有该项配置，肯呢个devtools不会起作用，即应用不会restart &ndash;&gt;-->

                     <!--<fork>true</fork>-->

                 <!--</configuration>-->

                 <dependencies>

                     <!--springloaded  hot deploy -->

                     <dependency>

                         <groupId>org.springframework</groupId>

                         <artifactId>springloaded</artifactId>

                         <version>1.2.4.RELEASE</version>

                     </dependency>

                 </dependencies>

                 <executions>

                     <execution>

                         <goals>

                             <goal>repackage</goal>

                         <configuration>

                             <classifier>exec</classifier>

                         </configuration>

                     </execution>

                 </executions>

             </plugin>

         </plugins>

     </build>

 </project>

2、书写测试代码pojo（实体类）

 package com.easytest;

 import com.alibaba.fastjson.annotation.JSONField;

 import java.util.Date;

 /**

  * Created by liuya on 2018-01-17.

  */

 public class UserPoJo

 {

     private int userId;

     private String userName;

     @JSONField(format="yyyy-MM-dd HH:mm:ss")

     private Date createTime;

     public Date getCreateTime() {

         return createTime;

     }

     public void setCreateTime(Date createTime) {

         this.createTime = createTime;

     }

     public int getUserId() {

         return userId;

     }

     public void setUserId(int userId) {

         this.userId = userId;

     }

     public String getUserName() {

         return userName;

     }

     public void setUserName(String userName) {

         this.userName = userName;

     }

     @Override

     public String toString() {

         return "UserPoJo{" +

                 "userId=" + userId +

                 ", userName='" + userName + '\'' +

                 ", createTime=" + createTime +

                 '}';

     }

 }

3、书写测试服务器

 package com.easytest;

 import com.alibaba.fastjson.serializer.SerializerFeature;

 import com.alibaba.fastjson.support.config.FastJsonConfig;

 import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;

 import org.springframework.boot.SpringApplication;

 import org.springframework.boot.autoconfigure.SpringBootApplication;

 import org.springframework.http.MediaType;

 import org.springframework.http.converter.HttpMessageConverter;

 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

 import java.util.ArrayList;

 import java.util.List;

 @SpringBootApplication

 public class RebushuApplication extends WebMvcConfigurerAdapter {

     /**

      //     * 在这里我们使用 @Bean注入 fastJsonHttpMessageConvert

      //     * @return

      //     */

     @Override

     public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

         // 1、需要先定义一个 convert 转换消息的对象;

         FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();

         //2、添加fastJson 的配置信息，比如：是否要格式化返回的json数据;

         FastJsonConfig fastJsonConfig = new FastJsonConfig();

         fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);

         //处理中文乱码

         List<MediaType> fastMediaTypes = new ArrayList<>();

         fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);

         fastConverter.setSupportedMediaTypes(fastMediaTypes);

         //3、在convert中添加配置信息.

         fastConverter.setFastJsonConfig(fastJsonConfig);

         HttpMessageConverter<?> converter = fastConverter;

         converters.add(fastConverter);

     }

     public static void main(String[] args) {

         SpringApplication.run(RebushuApplication.class, args);

     }

 }

4、书写controller代码

 package com.easytest;

 import org.springframework.web.bind.annotation.RequestMapping;

 import org.springframework.web.bind.annotation.RestController;

 import java.util.Date;

 /**

  * Created by liuya on 2018-01-16.

  *

  *  测试用的一个helloworld例子

  */

 @RestController

 public class ControllerJson {

     @RequestMapping("user2")

     public UserPoJo hello(){

         //实体类赋值

         UserPoJo userPoJo  = new UserPoJo();

         userPoJo.setUserId(111);

         userPoJo.setUserName("王小二");

         userPoJo.setCreateTime(new Date());

         //返回实体类

         return userPoJo;

     }

 }

5、编译器配置(详见:http://www.cnblogs.com/liuyangfirst/p/8318664.html)

6、maven启动,在编译器右侧栏点开右侧栏

7、访问网页测试一下是否联通

8、controller中加如下内容，然后F5刷新界面，如图就是成功实现热部署
