Spring Boot 使用json框架fastjson

使用Json框架Fastjson替换Spring Boot默认Jackson

1. 第一种方法

/** * 配置类：利用fastjson替换springboot默认的jackson * Created by gaozhy on 2017/6/4 0004. */@Configurationpublic class WebMvcConfig extends WebMvcConfigurerAdapter {    public void configureMessageConverters(List<HttpMessageConverter<?>> converters){        // 1. 创建json转换器        FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();        FastJsonConfig fastJsonConfig = new FastJsonConfig();        // 2. 格式化相应json格式        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);        // 3. 处理中文乱码        ArrayList<MediaType> mediaTypes = new ArrayList<MediaType>();        mediaTypes.add(MediaType.APPLICATION_JSON_UTF8);        converter.setSupportedMediaTypes(mediaTypes);        // 4. 配置converter        converter.setFastJsonConfig(fastJsonConfig);        // 5. 添加        converters.add(converter);    }}

/** * springboot启动类 *@SpringBootApplicationpublic class SpringBoot01Application{    public static void main(String[] args){        SpringApplication.run(SpringBoot01Application.class,args);    }}

2. 第二种办法

@SpringBootApplicationpublic class SpringBoot01Application{    /**     * 使用fastjson     * @return     */    @Bean    public HttpMessageConverters createMessageConverters(){        // 1. 创建json转换器        FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();        FastJsonConfig fastJsonConfig = new FastJsonConfig();        // 2. 格式化相应json格式        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);        // 3. 处理中文乱码        ArrayList<MediaType> mediaTypes = new ArrayList<MediaType>();        mediaTypes.add(MediaType.APPLICATION_JSON_UTF8);        converter.setSupportedMediaTypes(mediaTypes);        // 4. 配置converter        converter.setFastJsonConfig(fastJsonConfig);        // 5. 创建转换器        HttpMessageConverter httpMessageConverter = converter;        return new HttpMessageConverters(httpMessageConverter);    }    public static void main(String[] args){        SpringApplication.run(SpringBoot01Application.class,args);    }}
