使用struts中的validate方法判断密码不为空

index.jsp:用于输入用户和密码

show.jsp:用于验证通过后显示

<body>
用户${username}<br>
密码${password}<br>
</body>

yanzheng.java:对提交的界面进行验证

package com;

import com.opensymphony.xwork2.ActionSupport;

public class yanzheng extends ActionSupport {

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;
}

@Override
public void validate() {
if(this.password==null||("").equals(this.password)){
this.addActionError("not null");
}
}
@Override
public String execute() throws Exception {
return "success";
}

}

struts.xml配置:连接jsp与struts.xml

<struts>
<package name="struts2" extends="struts-default">
<action name="tijiao" class="com.yanzheng">
<result name="success">/show.jsp</result>
<result name="input">/index.jsp</result>
</action>
</package>
</struts>
