Struts2的自动装配

第一种 零散参数的自动装配

action方法

/**
 *
 * 零散参数自动装配
 */
public class LoginAction implements Action {
    private String username;
    private String password;
    public String execute() throws Exception {
        if (username.equals("admin") && password.equals("admin")){
            return SUCCESS;
         }else {
            return LOGIN;
        }
    }

    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;
    }
}

struts.xml的action配置文件

<!--零散参数的自动装配-->
<action name="login" class="cn.sjl.day01.controller.LoginAction">
    <result name="success">day01/success.jsp</result>
    <result name="login">day01/login.jsp</result>
</action>

jsp页面

<%@taglib prefix="s" uri="/struts-tags" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<s:form name="form1" namespace="/" method="post" action="login">
    请输入用户名： <s:textfield name="username"></s:textfield> <br/>
    <s:password name="password"></s:password><br/>
    <s:submit value="登陆"></s:submit>
</s:form>
</body>
</html>


第二种   JavaBean（对象）类型的自动装配

Action方法

public class UserInfo {
    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;
    }
}

/**
 *
 * JavaBean类型的自动装配
 */
public class LoginBeanAction implements Action{
    private UserInfo info;
    public String execute() throws Exception {
        if (info.getUsername().equals("admin")&& info.getPassword().equals("admin")){
            return SUCCESS;
        }else {
            return LOGIN;
        }
    }

    public UserInfo getInfo() {
        return info;
    }
    public void setInfo(UserInfo info) {
        this.info = info;
    }
}

struts.xml的action配置

<!--JavaBean类型的自动装配-->
<action name="loginbean" class="cn.sjl.day01.controller.LoginBeanAction">
    <result name="success">day01/success.jsp</result>
    <result name="login">day01/loginbean.jsp</result>
</action>

jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<head>
    <title>Title</title>
</head>
<body>
<s:form name="form1" namespace="/" method="post" action="loginbean">
    请输入用户名： <s:textfield name="info.username"></s:textfield> <br/>
    <s:password name="info.password"></s:password><br/>
    <s:submit value="登陆"></s:submit>
</s:form>
</body>
</html>

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>

<head>
    <title>成功 </title>

<body>
登录成功

以上就是struts2自动装配，总体来说struts2自动装配还是挺简单的。
