Question

我的应用程序中有以下类映射。

 public class Source {
        // Header 
        private String one;
        private String two;
        // Body
        private String three;
        private String four;
        private String five;
        private String six;
        // Getters & Setters
    }
public class Destination {
       private Header header;
       private Body body;
       // Getter & Setter
}
public class Header {
    private String one;
    private String two;
    // Getter & Setters
}
public class Body {
    private String three;
    private String four;
    private String five;
    private String six;
    // Getter & Setters
}

我必须使用Dozer从源bean转换为目标bean。这个用例可能吗？我知道Dozer默认具有双向映射，我们可以单向映射。但是，与简单的java代码相比，写一个单向特定映射xml是值得的，将数据从一个bean复制到另一个bean？请建议。

映射XML

DECLARE mlat FLOAT(10,6) DEFAULT 0.00084;
