struts2验证 标签 国际化demo
基本文件结构如下图
login.java
package lingzhi; import javax.servlet.jsp.tagext.TryCatchFinally; import com.opensymphony.xwork2.ActionSupport; public class Login extends ActionSupport { public String execute() throws Exception{ setMessage(getText(MESSAGE)); if(isInvalid(getUsername())) return INPUT; if(isInvalid(getPassword())) return INPUT; return SUCCESS; } private boolean isInvalid(String value){ return (!value.equals("www")); } public static final String MESSAGE = "HelloWorld.message"; private String message; private 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; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } }
