推土机将类字段嵌套到平面地图。使用推土机API进行类映射

Question

我想让推土机地图成为我的职业：

public class A {
  private B someB;
  private String someAText;
}

public class B {
  private String someBText;
}

到生成的Map.class，如下所示：

"someAText" => "someATextValue"
"someBText" => "someBTextValue"

.

也就是说，我正在尝试将嵌套类的字段映射到平面Map键目标。我使用的是JavaAPI的Dozer，而不是xml。我无法找到适当的构建器配置来管理它。基本代码类似于：

beanMappingBuilder = new BeanMappingBuilder() {
  @Override
  protected void configure() {
    mapping(B.class, Map.class, TypeMappingOptions.oneWay(), mapNull(true));
    mapping(A.class, Map.class, TypeMappingOptions.oneWay(), mapNull(true));
  }
 }

我建议您尝试以下配置：

beanMappingBuilder = new BeanMappingBuilder() {

  @Override
  protected void configure() {
    // 'A > Map' mapping
    mapping(A.class, Map.class, TypeMappingOptions.oneWay(), TypeMappingOptions.mapNull(true))
      .fields("someAText", "someATextValue")
      .fields("someB.someBText", "someBTextValue");

    // 'B > Map' mapping
    mapping(B.class, Map.class, TypeMappingOptions.oneWay(), TypeMappingOptions.mapNull(true))
      .fields("someBText", "someBTextValue");
  }
}
