基于struts2的全局自定义类型转换器
实体bean的
package com.bean;public class User {private :arrow: String username;private String password;public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}struts2.xml配置文件

package com.struts2.strutsconverter;import java.util.Map;import org.apache.struts2.util.StrutsTypeConverter;import com.bean.User;public class Struts2Converter extends StrutsTypeConverter {@Overridepublic Object convertFromString(Map context, String[] values, Class toClass) {User user = new User();String[] strValue = values[0].split(",");user.setUsername(strValue[0]);user.setPassword(strValue[1]);return user;}@Overridepublic String convertToString(Map context, Object o) {User user = (User)o;return user.getUsername() + "," + user.getPassword();}}试图jsp

xwork-conversion.properties
具体配置为：
com.bean.User=com.struts2.strutsconverter.Struts2Converter
