SpringBoot之fastjson（M）

1.默认springboot的json

2.配置com.alibaba.fastjson的json

A)配置方法

pom.xml添加jar包

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

（1）启动类继承extends WebMvcConfigurerAdapter

（2）覆盖方法configureMessageConverters

@Override    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();        FastJsonConfig fastJsonConfig = new FastJsonConfig();        fastJsonConfig.setSerializerFeatures(                SerializerFeature.PrettyFormat        );        fastConverter.setFastJsonConfig(fastJsonConfig);        converters.add(fastConverter);        super.configureMessageConverters(converters);    }
