一些小坑

Posted 2020-10-11 Mr.yang.localhost

一、使用jackson反序列化时存在多余字段：

Unrecognized field "xxx" (……), not marked as ignorable (5 known properties: "xxxxxxxxx",

反序列化字段未匹配上，忽略掉这些字段：

public class JsonUtil {

    public static final ObjectMapper objectMapper;

    static {
        objectMapper = new ObjectMapper();
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    }

}

二、swagger配置开发环境：

@Profile("dev")  //指定只可以在dev环境看到接口doc

@Configuration
@EnableSwagger2
@Profile("dev")
@ComponentScan("com.xxx.xxx.controller")
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.xxx.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        ApiInfo apiInfo = new ApiInfoBuilder().title("Service APIs")
                .description("Service APIs")
                .license("xxx")
                .licenseUrl("http://www.xxx.com")
                .version("1.0")
                .build();

        return apiInfo;
    }
}

 三、modelmapper的严格匹配：

    private ModelMapper mapper;

    /**
     * init mapper
     */
    public DemoController() {
        this.mapper = new ModelMapper();
        this.mapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);
    }
