Question

我想排除所有'createdDate'字段在我的所有映射字段中反序列化：

与此类似：

hash_hmac()

因此，在查询时可以看到该字段但不可更新。

有没有办法在全局范围内执行此操作而无需在每个映射上指定它？

Answer 1

将所有公共字段移至源类和目标类的超类。并为超类创建映射。完整的示例可以在Dozer fields - Global Exclude Example

找到

第1步：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
}

第2步：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
}

第3步：创建映射

<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns="http://dozer.sourceforge.net"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://dozer.sourceforge.net
          http://dozer.sourceforge.net/schema/beanmapping.xsd">
     <mapping>
            <class-a>com.codesimplify.dozersamples.fieldexclude.AddressType</class-a>
            <class-b>com.codesimplify.dozersamples.fieldexclude.Address</class-b>   
    </mapping>

   <mapping>
    <class-a>com.codesimplify.dozersamples.fieldexclude.BaseType</class-a>
    <class-b>com.codesimplify.dozersamples.fieldexclude.BaseDomain</class-b>
    <field-exclude type="one-way">
        <a>createdDate</a>
        <b>createdDate</b>
    </field-exclude>    
    </mapping>
</mappings>

推土机：是否可以单向排除所有映射类的字段？
