尝试在mapstruct中为目标和源为字符串的所有字段创建通用映射器

public class SourceObject {
    private String field1;
    private String field2;
    // 其他字段和对应的getter和setter方法
}

public class TargetObject {
    private String field1;
    private String field2;
    // 其他字段和对应的getter和setter方法
}

@Mapper

    TargetObject map(SourceObject source);
}

@Mapper
public interface StringMapper {
    StringMapper INSTANCE = Mappers.getMapper(StringMapper.class);

    @Mapping(source = "field1", target = "field1")
    @Mapping(source = "field2", target = "field2")
    TargetObject map(SourceObject source);
}

SourceObject source = new SourceObject();
source.setField1("value1");
source.setField2("value2");

TargetObject target = StringMapper.INSTANCE.map(source);
System.out.println(target.getField1()); // 输出：value1
System.out.println(target.getField2()); // 输出：value2
