拦截器 拦截器分同步拦截器和异步拦截器； HandlerInterceptor 方法和执行时机 可以看DispathcerServlet的原来确定它的三个方法的执行时机； AsynHandlerInterceptor 看注释，主要用来清理在并发环境加清理ThreadLocal的数据； ResponseBodyAdvice 对返回值备注了@ResponseBody或者返回ResponseEntity做了一些加工； 会在使用消息转换器转换为json数据之前进行数据转换输出； package com.springbootpractice.interceptor.config; import com.fasterxml.jackson.core.JsonProcessingException; import com.fasterxml.jackson.databind.ObjectMapper; import com.springbootpractice.interceptor.config.interceptor.MyInterceptor; import lombok.SneakyThrows; import org.springframework.context.annotation.Configuration; import org.springframework.core

EXC_BAD_ACCESS in parent class init() with Xcode 10.2

由 别说谁变了你拦得住时间么 提交于 2020-01-01 12:41:28
问题 I’ve been pulling my hair on a weird bug in Xcode 10.2. I’ve had this swift util method to decode JSON objects using ObjectMapper as I can’t call ObjectMapper from ObjectiveC: @objc static func mapModel(fromClass: AnyClass, jsonDict: [String : Any]) -> Any? { guard let mappableClass = fromClass as? Mappable.Type else { fatalError("class \(fromClass) is not Mappable") } return mappableClass.init(JSON: jsonDict) } Here's how I call it in ObjectiveC: FullUser *object = [ModelMapperHelper

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 处理数据库中Date类型字段转换成时间戳问题 有两种方式可以解决日期转换Json问题： 1、（不推荐）局部修改，自定义注解进行将日期类型转换为Date类型。 2、（强烈推荐）全局修改，用MappingJackson2HttpMessageConverter配置在XML（SpringMVC）或者配置在Application.Java启动类（Spring boot、Spring cloud）。 配置在Application.Java启动类（Spring boot、Spring cloud）： @Bean public MappingJackson2HttpMessageConverter getMappingJackson2HttpMessageConverter() { MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter(); //设置日期格式 ObjectMapper objectMapper = new ObjectMapper(); SimpleDateFormat smt = new SimpleDateFormat("yyyy
