【Dozer】数据映射之bean映射

项目研发过程中，避免不了和第三方系统交互，那么就会出现对同一字段，命名方式不同了，这个是比较让人头疼的事情，所以，今天就学习一下数据映射插件Dozer。

直接上代码：

1、maven引入dozer jar包：

<dependency>
     <groupId>com.github.dozermapper</groupId>
     <artifactId>dozer-core</artifactId>
     <version>6.4.0</version>
</dependency>

2、java代码：

package cn.gtmap.estateplat.olcommon.util;

import com.github.dozermapper.core.DozerBeanMapperBuilder;
import com.github.dozermapper.core.Mapper;
import com.github.dozermapper.core.Mapping;
import org.apache.commons.collections.CollectionUtils;
import org.springframework.stereotype.Component;

import java.util.List;

/**

@Component
public class DozerUtils {


    /**

      */

    public static void main(String[] args){
        Mapper mapper = DozerBeanMapperBuilder.buildDefault();
        A a = new A();
        a.setStudentName("张三");
        a.setAge(12);
        B b = mapper.map(a, B.class);
        System.out.println(b);
    }


    static class A{
        @Mapping("name")
        private String studentName;
        private Integer age;

        public String getStudentName() {
            return studentName;
        }

        public void setStudentName(String studentName) {
            this.studentName = studentName;
        }

        public Integer getAge() {
            return age;
        }

        public void setAge(Integer age) {
            this.age = age;
        }

        @Override
        public String toString() {
            return "A{" +
                    "studentName='" + studentName + '\'' +
                    ", age=" + age +
                    '}';
        }
    }

    static class B{
        private String name;
        private Integer age;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public Integer getAge() {
            return age;
        }

        public void setAge(Integer age) {
            this.age = age;
        }

        @Override
        public String toString() {
            return "B{" +
                    "name='" + name + '\'' +
                    ", age=" + age +
                    '}';
        }
    }
}
