orika实现对象复制
2024-10-16 20:03:32
1、新建maven工程orika-demo，引入orika依赖，其中pom.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion> <groupId>orika.demo</groupId>
<artifactId>orika-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>ma.glasnost.orika</groupId>
<artifactId>orika-core</artifactId>
<version>1.4.1</version>
</dependency>
</dependencies>
</project>
2、测试场景一：类名不同，属性完全相同的复制
public class UserDTO {
private String name;
private String sex;
public UserDTO(String name, String sex) {
this.name = name;
this.sex = sex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserDTO{" +
"name='" + name + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
public class UserDO {
private String name;
private String sex;
public UserDO(String name, String sex) {
this.name = name;
this.sex = sex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserDO{" +
"name='" + name + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
public class Test {
public static void main(String[] args){
MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
UserDTO userDTO = new UserDTO("张三","男");
UserDO userDO = mapperFactory.getMapperFacade().map(userDTO,UserDO.class);
System.out.println(userDO.toString());
}
}
UserDO{name='张三', sex='男'}
3、测试场景二：类名不同，部分属性不同的复制
public class UserDTO {
private String name;
private String sex;
public UserDTO(String name, String sex) {
this.name = name;
this.sex = sex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserDTO{" +
"name='" + name + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
public class NewUserDTO {
private String name;
private String newSex;
public NewUserDTO(String name, String newSex) {
this.name = name;
this.newSex = newSex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNewSex() {
return newSex;
}
public void setNewSex(String newSex) {
this.newSex = newSex;
}
@Override
public String toString() {
return "NewUserDTO{" +
"name='" + name + '\'' +
", newSex='" + newSex + '\'' +
'}';
}
}
public class Test {
public static void main(String[] args){
MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
UserDTO userDTO = new UserDTO("张三","男");
//如果不使用byDefault,则只会拷贝被field配置的属性,最后使用register使其生效
mapperFactory.classMap(UserDTO.class,NewUserDTO.class).field("sex", "newSex").byDefault().register();
NewUserDTO newUserDTO = mapperFactory.getMapperFacade().map(userDTO,NewUserDTO.class);
System.out.println(newUserDTO.toString());
}
}
NewUserDTO{name='张三', newSex='男'}
4、测试场景三：集合复制，集合内类的属性名相同
public class UserDTO {
private String name;
private String sex;
public UserDTO(String name, String sex) {
this.name = name;
this.sex = sex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserDTO{" +
"name='" + name + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
public class UserDO {
private String name;
private String sex;
public UserDO(String name, String sex) {
this.name = name;
this.sex = sex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserDO{" +
"name='" + name + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
public class Test {
public static void main(String[] args){
MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
List<UserDTO> userDTOList = new ArrayList<UserDTO>();
userDTOList.add(new UserDTO("张三","男"));
userDTOList.add(new UserDTO("李英","女"));
List<UserDO> userDOList = mapperFactory.getMapperFacade().mapAsList(userDTOList,UserDO.class);
System.out.println(userDOList.toString());
}
}
[UserDO{name='张三', sex='男'}, UserDO{name='李英', sex='女'}]
5、测试场景四：集合复制，集合内类的属性名部分不同
public class UserDTO {
private String name;
private String sex;
public UserDTO(String name, String sex) {
this.name = name;
this.sex = sex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserDTO{" +
"name='" + name + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
public class NewUserDTO {
private String name;
private String newSex;
public NewUserDTO(String name, String newSex) {
this.name = name;
this.newSex = newSex;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNewSex() {
return newSex;
}
public void setNewSex(String newSex) {
this.newSex = newSex;
}
@Override
public String toString() {
return "NewUserDTO{" +
"name='" + name + '\'' +
", newSex='" + newSex + '\'' +
'}';
}
}
public class Test {
public static void main(String[] args){
MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
List<UserDTO> userDTOList = new ArrayList<UserDTO>();
userDTOList.add(new UserDTO("张三","男"));
userDTOList.add(new UserDTO("李英","女"));
mapperFactory.classMap(UserDTO.class, NewUserDTO.class).field("sex","newSex").byDefault().register();
List<NewUserDTO> newUserDTOList = mapperFactory.getMapperFacade().mapAsList(userDTOList,NewUserDTO.class);
System.out.println(newUserDTOList.toString());
}
}
[NewUserDTO{name='张三', newSex='男'}, NewUserDTO{name='李英', newSex='女'}]
6、测试场景五：类复制，类里面包含集合属性，类的属性部分不同，集合属性名字相同，但是集合里面的类属性部分不同
public class UserListDTO {
private String listName;
private List<UserDTO> userList;
public String getListName() {
return listName;
}
public void setListName(String listName) {
this.listName = listName;
}
public List<UserDTO> getUserList() {
return userList;
}
public void setUserList(List<UserDTO> userList) {
this.userList = userList;
}
@Override
public String toString() {
return "UserListDTO{" +
"listName='" + listName + '\'' +
", userList=" + userList +
'}';
}
}
public class NewUserListDTO {
private String newListName;
private List<NewUserDTO> userList;
public String getNewListName() {
return newListName;
}
public void setNewListName(String newListName) {
this.newListName = newListName;
}
public List<NewUserDTO> getUserList() {
return userList;
}
public void setUserList(List<NewUserDTO> userList) {
this.userList = userList;
}
@Override
public String toString() {
return "NewUserListDTO{" +
"newListName='" + newListName + '\'' +
", userList=" + userList +
'}';
}
}
public class Test {
public static void main(String[] args){
MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
List<UserDTO> userDTOList = new ArrayList<UserDTO>();
userDTOList.add(new UserDTO("张三","男"));
userDTOList.add(new UserDTO("李英","女"));
UserListDTO userListDTO = new UserListDTO();
userListDTO.setListName("list001");
userListDTO.setUserList(userDTOList);
mapperFactory.classMap(UserDTO.class, NewUserDTO.class).field("sex","newSex").byDefault().register();
mapperFactory.classMap(UserListDTO.class, NewUserListDTO.class).field("listName","newListName").byDefault().register();
NewUserListDTO newUserListDTO = mapperFactory.getMapperFacade().map(userListDTO,NewUserListDTO.class);
System.out.println(newUserListDTO.toString());
}
}
NewUserListDTO{newListName='list001', userList=[NewUserDTO{name='张三', newSex='男'}, NewUserDTO{name='李英', newSex='女'}]}
