SpringBoot 添加fastjson

1.先在项目中添加fastjson依赖：

<dependency>

	<groupId>com.alibaba</groupId>

	<artifactId>fastjson</artifactId>

	<version>${fastjson.version}</version>

</dependency>

2.1第一种方法，让入口类实现WebMvcConfigure接口，并重写configureMessageConverters方法：

public class App implements WebMvcConfigurer{

     ......

}

重写方法：

public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

		//第一种配置fastJson方法

		FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();

		FastJsonConfig fastJsonConfig = new FastJsonConfig();

		fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);

		//处理中文乱码问题

        List<MediaType> fastMediaTypes = new ArrayList<MediaType>();

        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);

        fastJsonHttpMessageConverter.setSupportedMediaTypes(fastMediaTypes);

		fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);

		converters.add(fastJsonHttpMessageConverter);

}

2.2第二种方法，直接在入口类加入@Bean注解并加入方法：

@Bean

public HttpMessageConverters fastJsonHttpMessage() {

		FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();

		FastJsonConfig fastJsonConfig = new FastJsonConfig();

		fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);

		//处理中文乱码问题

        List<MediaType> fastMediaTypes = new ArrayList<MediaType>();

        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);

        fastJsonHttpMessageConverter.setSupportedMediaTypes(fastMediaTypes);

		fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);

		return new HttpMessageConverters(fastJsonHttpMessageConverter);

}
