推土机：是否可以在所有映射的类中单向排除字段？

Question

我想从所有映射字段上反序列化的过程中排除所有“ createdDate”字段：

与此类似：

<field-exclude type="one-way""> <a>createdDate</a> <b>createdDate</b> </field-exclude>

因此，查询时该字段可见，但不可更新。

有没有一种全局方法可以不必在每个映射上都指定它？

Answer 1

将所有公共字段移至源类和目标类的超类。 并为超级类创建映射。 完整示例可在推土机字段中找到-全局排除示例

步骤1：来源POJO：

    //PersonType.java
public class AddressType extends BaseType{

    private String addrLine1;
    private String city;
    private String state;
    private int zipCode;
    // Setter and Getter methods are removed
}
// BaseType.java
public class BaseType { 
        private String createdDate;
    // Setter and Getter methods are removed
}

步骤2：定位POJO：

// Address.java
public class Address extends BaseDomain{

    private String addrLine1;
    private String city;
    private String state;
    private int zip5;
// Setter and Getter methods are removed
}
//BaseDomain.java
public class BaseDomain {   
    private String createdDate;
// Setter and Getter methods are removed
}

步骤3：建立对应
