Spring Boot集成FastJson

1. 如何集成fastjson?

1.1 在pom.xml文件中加入:

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.15</version>
</dependency>

1.2 在启动类中加入:

package com.npf.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.context.annotation.Bean;
import org.springframework.http.converter.HttpMessageConverter;

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;

/**
 * 
 * @author Jack
 *
 */
@SpringBootApplication
public class SpringBootBootstrap {
    
    public static void main(String[] args) {
        SpringApplication.run(SpringBootBootstrap.class, args);
    }
    
    @Bean
    public HttpMessageConverters fastJsonHttpMessageConverters(){
        //1. 需要定义一个converter转换消息的对象
        FastJsonHttpMessageConverter fasHttpMessageConverter = new FastJsonHttpMessageConverter();
        
        //2. 添加fastjson的配置信息，比如:是否需要格式化返回的json的数据
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        
        //3. 在converter中添加配置信息
        fasHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
        HttpMessageConverter<?> converter = fasHttpMessageConverter;
        return new HttpMessageConverters(converter);
    }
}

1.3 在实体类中可以加入定制Json格式化

package com.npf.springboot.entity;

import com.alibaba.fastjson.annotation.JSONField;

public class User {
    
    private int id;
    
    private String name;
    
    private String password;
    
    @JSONField(format="yyyy-MM-dd: HH:mm")
    private java.util.Date createTime;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public java.util.Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(java.util.Date createTime) {
        this.createTime = createTime;
    }
}

1.4 运行测试
