问题：用spring定义返回类型为String，预期返回: zhangsan,结果返回:"zhangsan"
原因: 使用公司研发框架，对字符串类型定义做了处理，导致返回字符串加双引号(既jsonString类型字符串),怎么定义实现WebMvcConfigurer 做处理都无法转换，是由于框架里面已经对这个做了实现并制定优先级为0，导致自己写的无效，框架部分代码实现如下
public class FastJsonDesensitizationConfigurationimplements WebMvcConfigurer {
public FastJsonDesensitizationConfiguration() {
}
public void extendMessageConverters(List> converters) {
FastJsonHttpMessageConverter fastJsonConverter =new FastJsonHttpMessageConverter();
List mediaTypes =new ArrayList();
mediaTypes.add(MediaType.APPLICATION_JSON);
mediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
mediaTypes.add(new MediaType("application", "*+json"));
fastJsonConverter.setSupportedMediaTypes(mediaTypes);
FastJsonConfig fastJsonConfig =new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(new SerializerFeature[]{SerializerFeature.BrowserSecure, SerializerFeature.WriteMapNullValue, SerializerFeature.PrettyFormat, SerializerFeature.DisableCircularReferenceDetect});
fastJsonConfig.setSerializeFilters(new SerializeFilter[]{FastJsonFilterForDesensitize.getInstance()});
fastJsonConverter.setFastJsonConfig(fastJsonConfig);
converters.add(0, fastJsonConverter);
}
}
解决问题：在请求参数里面加 produces = MediaType.TEXT_PLAIN_VALUE配置，指定返回参数格式，代码截图如下
