[alibaba/fastjson]springboot 中使用FastJsonView注解无效

在springboot中通过bean设置将解析改为fastjson。fastjson版本为1.2.36 Controller端代码如下，程序正常运行，但是字段还是返回了Test中的全部字段内容。 @RequestMapping("ob") @FastJsonView( include = {@FastJsonFilter(clazz = Test.class,props={"descn"})}, exclude = {@FastJsonFilter(clazz = Test.class,props = {"id","name"})} ) public @ResponseBody Test ob(){ Test test = new Test(); test.setId(22); test.setName("badaf"); test.setDescn("hjhh"); test.setAaa("aaa"); return test;

@smallsun848 配置 FastJsonHttpMessageConverter、FastJsonViewResponseBodyAdvice 了吗？

@lihengming FastJsonHttpMessageConverter配置如下，FastJsonViewResponseBodyAdvice 需要怎么配置？

@SpringBootApplication @MapperScan("com.example.test1.dao") public class Test1Application {

public static void main(String[] args) {
    SpringApplication.run(Test1Application.class, args);
}

@Bean
public HttpMessageConverters fastJsonHttpMessageConverters() {
    FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
    FastJsonConfig fastJsonConfig = new FastJsonConfig();
    fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat,SerializerFeature.WriteMapNullValue);
    fastConverter.setFastJsonConfig(fastJsonConfig);
    HttpMessageConverter<?> converter = fastConverter;
    return new HttpMessageConverters(converter);
}

}

问题解决了。因为FastJsonViewResponseBodyAdvice 配置了component，而springboot默认不会去扫描，指定了扫描的路径就可以了。

@SpringBootApplication @MapperScan("com.example.test1.dao") @ComponentScan({"com.alibaba.fastjson.support.spring","com.example.test1.controller"}) public class Test1Application {

I think so： @ControllerAdvice MyFastJsonViewResponseBodyAdvice extends FastJsonViewResponseBodyAdvice{ }

springboot版本: 2.0.1.RELEASE fastjson版本: 1.2.46

FastJsonViewResponseBodyAdvice

@RestControllerAdvice
public class MyFastJsonViewResponseBodyAdvice extends FastJsonViewResponseBodyAdvice {
}

TsetController

@RestController
@RequestMapping("/test")
public class TestController {

    private static final Logger logger = Logger.getLogger(TestController.class);

    @GetMapping(path = "address")
    @FastJsonView(include = @FastJsonFilter(clazz = Address.class, props = {"city"}))
    public Address testFastJsonView() {

        Address address = new Address();
        address.setCity("city");
        address.setStreet("street");
        address.setDistrict("district");
        address.setNumber("number");
        address.setComment("comment");

        return address;

    }
}

Test

@RunWith(SpringRunner.class)
@WebMvcTest(TestController.class)
public class AddressTest {

    @Autowired
    private MockMvc mvc;

    @Test
    public void testExample() throws Exception {
        MvcResult result = mvc.perform(MockMvcRequestBuilders.get("/test/address")
                .accept(MediaType.APPLICATION_JSON)).andReturn();

        System.out.println(result.getResponse().getContentAsString());
    }
}

Address的字段都输出了

{"city":"city","district":"district","street":"street","number":"number","comment":"comment"}

控制台中输出了 Detected ResponseBodyAdvice implementation in myFastJsonViewResponseBodyAdvice 但是我在FastJsonViewResponseBodyAdvice中的方法打断点，发现并没有执行到断点处。请问这是什么问题？是因为我配置有问题还是程序的问题？有什么解决方案吗？
