springboot 整合fastjson

个人觉得阿里爸爸的fastjson还是很好用的，所以这里就写一下sp集合fastjson的方法

首先在 gradle文件中加上fastjson 依赖

compile 'com.alibaba:fastjson:1.2.31'

其实springboot 整合fastjson 共有两种方法，现在就逐一说一下

1. 启动类继承extends WebMvcConfigurerAdapter 并且覆盖方法configureMessageConverters
2. 在App.java启动类中，注入Bean : HttpMessageConverters

现在说下第一种方法
在startApplication中

package smaug.service.provider.starts;import com.alibaba.fastjson.serializer.SerializerFeature;import com.alibaba.fastjson.support.config.FastJsonConfig;import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter4;import org.glassfish.jersey.servlet.ServletContainer;import org.glassfish.jersey.servlet.ServletProperties;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.web.servlet.ServletRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.ImportResource;import org.springframework.http.MediaType;import org.springframework.http.converter.HttpMessageConverter;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import smaug.service.config.jerseyConfig.AnnotationJerseyConfig;import java.nio.charset.Charset;import java.util.ArrayList;import java.util.List;/** * Created by naonao on 17/7/9. */@SpringBootApplication(scanBasePackages = {"smaug.service", "smaug.util", "smaug.config"})@MapperScan("smaug.service.provider.mapper")@ImportResource("classpath:spring-order-context.xml")public class OrderStartApplication extends WebMvcConfigurerAdapter{    public static void main(String[] args) {        SpringApplication.run(OrderStartApplication.class, args);    }    @Bean    public ServletRegistrationBean jerseyServlet() {        ServletRegistrationBean registration = new ServletRegistrationBean(new ServletContainer(), "/*");        registration.addInitParameter(ServletProperties.JAXRS_APPLICATION_CLASS, AnnotationJerseyConfig.class.getName());        return registration;    }    @Override    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {        super.configureMessageConverters(converters);        //定义一个convert 转换消息对象        FastJsonHttpMessageConverter4 fastConverter = new FastJsonHttpMessageConverter4();        FastJsonConfig jsonConfig = new FastJsonConfig();        jsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);        List<MediaType> types = new ArrayList<>();        types.add(MediaType.APPLICATION_JSON_UTF8);        fastConverter.setSupportedMediaTypes(types);        fastConverter.setFastJsonConfig(jsonConfig);        converters.add(fastConverter);    }}

第二种方法 在startAoolication 注入bean

package smaug.service.provider.starts;import com.alibaba.fastjson.serializer.SerializerFeature;import com.alibaba.fastjson.support.config.FastJsonConfig;import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter4;import org.glassfish.jersey.servlet.ServletContainer;import org.glassfish.jersey.servlet.ServletProperties;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.autoconfigure.web.HttpMessageConverters;import org.springframework.boot.web.servlet.ServletRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ImportResource;import org.springframework.http.converter.HttpMessageConverter;import smaug.service.config.jerseyConfig.AnnotationJerseyConfig;/** * Created by naonao on 17/7/9. */@SpringBootApplication(scanBasePackages = {"smaug.service", "smaug.util", "smaug.config"})@MapperScan("smaug.service.provider.mapper")@ImportResource("classpath:spring-order-context.xml")public class OrderStartApplication {    public static void main(String[] args) {        SpringApplication.run(OrderStartApplication.class, args);    }    @Bean    public ServletRegistrationBean jerseyServlet() {        ServletRegistrationBean registration = new ServletRegistrationBean(new ServletContainer(), "/*");        registration.addInitParameter(ServletProperties.JAXRS_APPLICATION_CLASS, AnnotationJerseyConfig.class.getName());        return registration;    }//    @Override//    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {//        super.configureMessageConverters(converters);//        //定义一个convert 转换消息对象//        FastJsonHttpMessageConverter4 fastConverter = new FastJsonHttpMessageConverter4();//        FastJsonConfig jsonConfig = new FastJsonConfig();//        jsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);//        List<MediaType> types = new ArrayList<>();//        types.add(MediaType.APPLICATION_JSON_UTF8);//        fastConverter.setSupportedMediaTypes(types);//        fastConverter.setFastJsonConfig(jsonConfig);//        converters.add(fastConverter);//    }    @Bean    public HttpMessageConverters fastJsonHttpMessageConverters() {        FastJsonHttpMessageConverter4 converter = new FastJsonHttpMessageConverter4();        FastJsonConfig jsonConfig = new FastJsonConfig();        jsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);        converter.setFastJsonConfig(jsonConfig);        HttpMessageConverter<?> httpConverter = converter;        return new HttpMessageConverters(httpConverter);    }}

测试方法 将返回类 如此书写 将返回实体类加入一下注解，如果请求结果没有该属性，就表明成功了

@JSONField(serialize = false)private String shopName;
