Springboot using Fastjson as the JSON parsing framework

Springboot using Fastjson as the JSON parsing framework

Springboot default comes with the JSON parsing framework, using Jackson by default, if you use Fastjson, you can configure the use

0, Build Springbboot Foundation Environment One, add dependence

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

Ii. configuration in the App.class (startup Class)

How to configure one (by inheritance)
1. Start class inheritance Webmvcconfigureradapter
2. Overriding the Configuremessageconverters method

    @Override    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {        super.configureMessageConverters(converters);        /*         * 1、需要先定义一个convert转换消息的对象         * 2、添加fastJson的配置信息，比如：是否要格式化返回json数据         * 3、在convert中添加配置信息         * 4、将convert添加到converters当中         *          */        //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json数据        FastJsonConfig fastJsonConfig = new FastJsonConfig();        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);        //3、在convert中添加配置信息.        fastConverter.setFastJsonConfig(fastJsonConfig);        //4、将convert添加到converters当中.        converters.add(fastConverter);    }  

Configuration Mode II (via @bean injection)

@Beanpublic HttpMessageConverters fastJsonHttpMessageConverters() {    // 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);           //3、在convert中添加配置信息.    fastConverter.setFastJsonConfig(fastJsonConfig);    HttpMessageConverter<?> converter = fastConverter;    return new HttpMessageConverters(converter);}

Second, the first configuration, test verification:

Prepare a controller.

import java.util.Date;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;import com.xujie.pojo.Demo;@RestController // 包括了@ResponseBody和Controllerpublic class UserController {        @GetMapping("/test")    public Demo test() {        Demo demo = new Demo();        demo.setId(1);        demo.setCreateTime(new Date());        demo.setName("demo22");        demo.setRemarks("这里是备注信息，不应该返回");        return demo;    }}

Start class notation

Import Java.util.list;import Org.springframework.boot.springapplication;import Org.springframework.boot.autoconfigure.springbootapplication;import Org.springframework.http.converter.httpmessageconverter;import Org.springframework.web.servlet.config.annotation.webmvcconfigureradapter;import Com.alibaba.fastjson.serializer.serializerfeature;import Com.alibaba.fastjson.support.config.FastJsonConfig; Import Com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; @SpringBootApplicationpublic class UserApplication extends Webmvcconfigureradapter {public static void main (string[] args) {Springapplication.run    (Userapplication.class, args);        } @Override public void Configuremessageconverters (list

Pojo class

import java.util.Date;import com.alibaba.fastjson.annotation.JSONField;public class Demo { private int id; private String name; //com.alibaba.fastjson.annotation.JSONField @JSONField(format="yyyy-MM-dd HH:mm") private Date createTime;//创建时间. /* * serialize:是否需要序列化属性. */ @JSONField(serialize=false) private String remarks;//备注信息. public String getRemarks() { return remarks; } public void setRemarks(String remarks) { this.remarks = remarks; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = 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; } }

Browser testing

* * Input Address: http://localhost:8080/test**

Return:
{ "createTime":"2018-02-23 12:06", "id":1, "name":"demo22" }
