Springboot 所遇问题备忘

1. org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json;charset=UTF-8' not supported

Application 继承 WebMvcConfigurationSupport，

重载函数configureMessageConverters

@Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);
        // 1、需要先定义一个·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json数据
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        // 3、在convert中添加配置信息.
        fastConverter.setFastJsonConfig(fastJsonConfig);
        // 4、将convert添加到converters当中.
        converters.add(fastConverter);
    }

2. Application 继承 WebMvcConfigurationSupport导致静态资源无法访问的问题

重载函数addResourceHandlers

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**")
                .addResourceLocations("classpath:/resources/")
                .addResourceLocations("classpath:/static/")
                .addResourceLocations("classpath:/public/");
        super.addResourceHandlers(registry);
    }
