# springboot全局配置Jackson未生效 #

### 1.application.yml配置项 ###

spring:
      jackson:
        date-format: yyyy-MM-dd HH:mm:ss
        time-zone: GMT+8
        default-property-inclusion: non_null

### 2.原因分析 ###

[引用SpringMVC官网说明][SpringMVC]  
Finally, if you opt out of the Spring Boot default MVC configuration by providing your own @EnableWebMvc configuration,you can take control completely and do everything manually by using getMessageConverters from WebMvcConfigurationSupport.

### 3.解决方式 ###

#### 3.1原因： ####

项目使用mvc拦截器，通过org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport配置，导致Jackson配置失效

/**
     * WebInterceptorConfig mvc请求拦截器.
     *
     * @author cs
     * @version 1.0
     * @date 2019-10-02 18:22
     * @description
     */
    @Configuration
    public class WebInterceptorConfig extends WebMvcConfigurationSupport {
         // 自己实现的拦截器
        @Autowired
        private UserAuthInterceptor userAuthInterceptor;
        // 添加权限拦截的管理器
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            registry.addInterceptor(userAuthInterceptor);
        }
    }

#### 3.2解决方式 ####

采用org.springframework.web.servlet.config.annotation.WebMvcConfigurer配置，Jackson配置成功

/**
     * WebInterceptorConfig mvc请求拦截器.
     *
     * @author cs
     * @version 1.0
     * @date 2019-10-02 18:22
     * @description
     */
    @Configuration
    public class WebInterceptorConfig implements WebMvcConfigurer {
        // 自己实现的拦截器
        @Autowired
        private UserAuthInterceptor userAuthInterceptor;
    
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            // 添加权限拦截的管理器
            InterceptorRegistration registration1 = registry.addInterceptor(userAuthInterceptor);
        }
    }
