struts.xml统一
<struts> <package name="result" namespace="/" extends="struts-default" > <!-- 转发 --> <action name="Demo6Action" class="com.future.api.Demo6Action" method="execute" > <result name="success">/index.jsp</result> </action> </package> </struts>
1、Action中定义属性然后定义属性的get set 方法获得
hello.jsp
<body> <form action="${pageContext.request.contextPath }/Demo6Action"> 姓名：<input type="text" name="name" /><br/> 年龄：<input type="text" name="age" /><br/> <input type="submit" value="提交" /> </form> </body>
Demo6Action.java
public class Demo6Action extends ActionSupport { private String name;//必须和jsp中的input标签中的name命名一样 private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } @Override public String execute() throws Exception { System.out.println("姓名：" + name); System.out.println("年龄：" + age); return SUCCESS; } }
2、定义Bean对象的方式获得
hello.jsp
<form action="${pageContext.request.contextPath }/Demo6Action"> <!-- 必须要和Action中定义的类对象名字一样 --> 姓名：<input type="text" name="user.name" /><br/> 年龄：<input type="text" name="user.age" /><br/> <input type="submit" value="提交" /> </form>
User.java
public class User { private String name; private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
Demo6Action.java
public class Demo6Action extends ActionSupport { //参数 private User user; public User getUser() { return user; } public void setUser(User user) { this.user = user; } @Override public String execute() throws Exception { System.out.println("姓名：" + user.getName()); System.out.println("年龄：" + user.getAge()); return SUCCESS; } }
3、模型驱动方式
hello.jsp
<form action="${pageContext.request.contextPath }/Demo6Action"> 姓名：<input type="text" name="user.name" /><br/> 年龄：<input type="text" name="user.age" /><br/> <input type="submit" value="提交" /> </form>
User.java
public class User { private String name; private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
Demo6Action.java
public class Demo6Action extends ActionSupport implements ModelDriven<User> { //成员变量 private User user = new User(); @Override public String execute() throws Exception { System.out.println("姓名：" + user.getName()); System.out.println("年龄：" + user.getAge()); return SUCCESS; } public User getModel() { return user; } }
4、使用集合方式获取
hello.jsp
<body> <form action="${pageContext.request.contextPath }/Demo6Action"> 姓名：<input type="text" name="list" /><br/> 年龄：<input type="text" name="list[1]" /><br/> 地址：<input type="text" name="map['address']" /><br/> 电话：<input type="text" name="map['phone']" /><br/> <input type="submit" value="提交" /> </form> </body>
Demo6Action.java
public class Demo6Action extends ActionSupport { private List<String> list; public List<String> getList() { return list; } public void setList(List<String> list) { this.list = list; } private Map<String, String> map; public Map<String, String> getMap() { return map; } public void setMap(Map<String, String> map) { this.map = map; } @Override public String execute() throws Exception { System.out.println("list：" + list); System.out.println("map:" + map); return SUCCESS; } }
