基于struts2的全局自定义类型转换器
实体bean的
struts2.xml配置文件
控制器actin
注册器
试图jsp
最后配置注册器，在classpath目录下配置如下配置文件，文件名为固定格式：
xwork-conversion.properties
具体配置为：
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;
}
}
