springboot 集成fastjson

一、引入包

    pom.xml 添加如下内容：

<!-- 引入fastjson -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.47</version>
</dependency>

二、配置fastjson

    Application.java类 添加如下代码：    

@Bean//使用@Bean注入fastJsonHttpMessageConvert
    public HttpMessageConverters fastJsonHttpMessageConverters() {
        //1.需要定义一个Convert转换消息的对象
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        //2.添加fastjson的配置信息，比如是否要格式化返回的json数据
//
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        //3.在convert中添加配置信息
        fastConverter.setFastJsonConfig(fastJsonConfig);

        HttpMessageConverter<?> converter = fastConverter;
        return new HttpMessageConverters(converter);
    }
