IntelliJ IDEA 2017版 springloaded实现热部署

1、配置pom.xml文档

<?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"

        <relativePath/> <!-- lookup parent from repository -->

    <properties>

        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <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>-->

            <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>-->

                <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>
                        </goals>
                        <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
