当业务简单的时候可以通过手动编码getter/setter函数来复制对象属性。但是当业务变的复杂对象属性变得很多那么手写复制属性代码不仅十分繁琐非常耗时间并且还可能容易出错。
为了解决这个痛点在项目初期项目的解决方法是随手写的转换工具函数根据变量名进行反射对基础类型和枚举的变量进行赋值。
总结下目前该工具函数的优缺点
优点
开发效率高随时想要转换的时候传入源对象以及指定class调用下函数即可。
缺点
项目中大量的反射会严重影响代码执行效率由于使用了反射所以成员变量的使用被追踪就很麻烦转换失败只有在运行中报错才会发现对于嵌套对象字段的情况无能为力只能对基础类型进行复制对字段名不一致的属性无法赋值 接下来就要介绍MapStruct 这个工具类这个工具类之所以运行速度与硬编码差不多这是因为MapStruct在编译期间就生成属性复制的代码运行期间就无需使用反射或者字节码技术从而确保了高性能。 另外由于编译期间就生成了代码所以如果有任何问题编译期间就可以提前暴露这对于开发人员来讲就可以提前解决问题而不用等到代码应用上线了运行之后才发现错误。
所以为了克服项目中当前函数的被提到的五个缺点笔者引入了MapStruct。
2. 如何引入MapStruct
只需要引入MapStruct的依赖同时由于MapStruct需要在编译器期间生成代码所以我们需要maven-compiler-plugin插件中配置
复制
// pom.xmldependencygroupIdorg.MapStruct/groupIdartifactIdMapStruct/artifactIdversion1.4.1.Final/version/dependency .高效性
1.编译期 自动生成映射代码
类型检查报错
2.灵活性支持复杂映射对象、集合列表 支持属性不同字段名、类型的赋值
3.直观性使用注解来定义映射规则 根据需求指定返回类型、忽略属性添加 条件判断来决定是否执行映射操作 package com.mdgyl.hussar.basic.supplier.changeorder.converter.struct;import com.mdgyl.common.util.DateUtils;
