Collections jaxb,集合的单项设置器
我想确保在我的对象上,xml元素内容以大写字母取消编组Collections jaxb,集合的单项设置器,collections,jaxb,getter-setter,Collections,Jaxb,Getter Setter,我想确保在我的对象上,xml元素内容以大写字母取消编组 public class SZM { String field01; @XmlElement(name="field01") public void setField01(String value) {this.field01 = value.toUpperCase();} public String getField01() {return field01;} 但是如何对集合中的每个项目执行相同的操作?
public class SZM {
String field01;
@XmlElement(name="field01")
public void setField01(String value) {this.field01 = value.toUpperCase();}
public String getField01() {return field01;}
但是如何对集合中的每个项目执行相同的操作?我希望从xml读取的任何值都是大写的
@XmlElement
ArrayList<String>collection01;
@xmlement
ArrayListcollection01;
提前感谢,,

全班同学,以防万一:
package test.jaxb;
import java.util.ArrayList;
import javax.xml.bind.annotation.*;
@XmlRootElement
public class SZM {
String field01;
@XmlElement(name="field01")
public void setField01(String value) {this.field01 = value.toUpperCase();}
public String getField01() {return field01;}
@XmlElement
ArrayList<String>collection01;
}
package test.jaxb;
导入java.util.ArrayList;
导入javax.xml.bind.annotation.*;
@XmlRootElement
公共级SZM{
字符串字段01;
@xmlement(name=“field01”)
public void setField01(字符串值){this.field01=value.toUpperCase();}
公共字符串getField01(){return field01;}
@XmlElement
ArrayListcollection01;
}
您可以使用XmlAdapter来操作字符串值:
StringCaseAdapter
import javax.xml.bind.annotation.adapters.XmlAdapter;
public class StringCaseAdapter extends XmlAdapter<String, String> {
@Override
public String unmarshal(String v) throws Exception {
return v.toUpperCase();
}
@Override
public String marshal(String v) throws Exception {
return v.toLowerCase();
}
}
