  • spring boot 与spring boot admin整合问题处理

    1.在整合springboot admin server时,发现admin client无法注册到admin server上

    查找原因后发现代码中报错:HttpMediaTypeNotAcceptableException: Could not find acceptable representation

    2.此时知道是返回给admin server类型时发生的错误,但是不知道admin server需要的是什么类型,所以重写WebMvcConfigurer

    解析全部类型查看返回类型是什么

     @Override
        public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
            for (HttpMessageConverter<?> converter : converters) {
                if (converter instanceof MappingJackson2HttpMessageConverter) {
                    converters.remove(converter);
                }
            }
            FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
            List<MediaType> supportedMediaTypes = new ArrayList<>();
            //解析全部类型
            supportedMediaTypes.add(MediaType.ALL);
    
            converter.setSupportedMediaTypes(supportedMediaTypes);
            FastJsonConfig fastJsonConfig = new FastJsonConfig();
            fastJsonConfig.setSerializerFeatures(SerializerFeature.WriteDateUseDateFormat,
                    SerializerFeature.WriteNullStringAsEmpty,
                    SerializerFeature.WriteMapNullValue,
                    SerializerFeature.DisableCircularReferenceDetect);
            //日期格式化
            fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss");
            converter.setFastJsonConfig(fastJsonConfig);
            converters.add(converter);
        }

    3.调用接口,返回结果成功,得知需要的类型为:application/vnd.spring-boot.actuator.v2+json

    4.添加对类型application/vnd.spring-boot.actuator.v2+json的解析

            //提供对admin的类型支持mediaType
            MediaType mediaType = MediaType.valueOf("application/vnd.spring-boot.actuator.v2+json");
            supportedMediaTypes.add(mediaType);
