谁借莪１个温暖的怀抱￠ 2022-07-11 14:10 198阅读 0赞

1、web创建工程  
2、导入Struts2的core包  
commons-fileupload-1.3.2.jar  
commons-io-2.4.jar  
commons-lang3-3.4.jar  
freemarker-2.3.23.jar  
javassist-3.20.0-GA.jar  
log4j-api-2.7.jar  
ognl-3.1.12.jar  
struts2-core-2.5.8.jar  
3、编写web.xml

<filter>
        <filter-name>attributedriven</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
      </filter>
      <filter-mapping>
        <filter-name>attributedriven</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>

4、创建JSP页面部分  
index.jsp  
login.jsp

//action对应struts.xml的action便签的name；
        <form action="Loginaction" method="post">
            账号<input type="text" name="name"><br>
            密码<input type="text" name="password"><br>
            <input type="submit" value="登录">
        </form>

success.jsp

5、创建Java类部分

Loginaction.java

//继承ActionSupport,对生成execute()和返回值 ，编写更规范
    public class Loginaction extends ActionSupport{ 
    
        //以下属性要的对应form表单的属性，并生成set、get方法
        private String name;
        public String password;
        //***************************
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getPassword() {
            return password;
        }
        public void setPassword(String password) {
            this.password = password;
        }
    
        //注意继承了ActionSupport，覆盖execute()方法
        @Override
        public String execute() throws Exception {
            // TODO 自动生成的方法存根
            if (name.equals("admin")&&password.equals("000")) {
                return SUCCESS;
            }
            return LOGIN;
        }
    
    }

6、创建struts.xml

<package name="attributedriven" namespace="/" extends="struts-default">
            <action name="Loginaction" class="com.dao.Loginaction">
                <result>/success.jsp</result>
                <result name="login">/login.jsp</result>
            </action>
        </package>
