SpringBoot如何使用Fastjson解析Json数据

方法一：

1.在pom.xml文件下添加依赖包

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

2.修改启动文件

package myshop;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 App extends WebMvcConfigurerAdapter{ @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { // TODO Auto-generated method stub super.configureMessageConverters(converters);FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastConfig = new FastJsonConfig(); fastConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fastConverter.setFastJsonConfig(fastConfig); converters.add(fastConverter); } public static void main(String[] args) { // TODO Auto-generated method stub SpringApplication.run(App.class, args); }}

3.修改实体类

package myshop.entity;import java.util.Date;import com.alibaba.fastjson.annotation.JSONField;/** * 用户类 * */public class User { private int id; private String username; private String password; @JSONField(format = 'yyyy-MM-dd HH-mm') private Date createTime; /** * 如果不希望返回remark信息 * serialize是否序列化 */ @JSONField(serialize = false) private String remark; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = createTime; } public String getRemark() { return remark; } public void setRemark(String remark) { this.remark = remark; }}

4.修改控制器

package myshop.controller;import java.util.Date;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import myshop.entity.User;/** * @RestController = @Controller + @RequestBody * */@RestControllerpublic class HelloController { /** * 建立请求映射 * */ @RequestMapping('/hello') public String hello() { return 'hello'; } /** * SpringBoot默认的解析框架Jackson * */ @RequestMapping('/getUser') public User gerUser() { User user = new User(); user.setId(1); user.setUsername('天恒'); user.setPassword('123456'); user.setCreateTime(new Date()); //此信息不会被返回 user.setRemark('这是备注信息！'); return user; }}

5.启动项目，在浏览器输入地址：http://localhost:8080/getUser

方法二：除了启动类，其余代码都和方法一一样

package myshop;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;@SpringBootApplicationpublic class App { @Bean public HttpMessageConverters fastJsonHttpMessageConverter() { FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); FastJsonConfig fastConfig = new FastJsonConfig(); fastConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fastConverter.setFastJsonConfig(fastConfig);HttpMessageConverter<?> converts = fastConverter; return new HttpMessageConverters(converts); } public static void main(String[] args) { // TODO Auto-generated method stub SpringApplication.run(App.class, args); }}
