7、请求参数接收

1. 对与请求参数,可以在所请求的action中添加相应的属性,写出get和set方法,在表单中配置name属性与action中属性的名称一致,提交到所在action即可;如下:

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

   public class HelloWorldAction {      private String name;      private int id;      public String getName() {          return name;      }        public void setName(String name) {          this .name = name;      }        public int getId() {          return id;      }        public void setId( int id) {          this .id = id;      } }

   则index.jsp中表单中应如下(对应属性名一致):

   1 2 3 4 5

   < form action = "${pageContext.request.contextPath }/control/department/list_execute.action" method = "post" >              < input type = "text" name = "id" >< br >              < input type = "text" name = "name" >< br >              < input type = "submit" value = "提交" > </ form >

   获取值:

   1 2	${id }</ br > ${name }

2. 对于复杂请求参数(以对象封装,实际应用如此;Person类必须使用默认构造器,不能自己添加构造器):

   1 2 3 4 5 6 7 8 9 10 11

   public class HelloWorldAction {          private Person person;            public Person getPerson() {          return person;      }        public void setPerson(Person person) {           this .person = person;      } }

   则表单如下:

   1 2 3 4 5

   < form action = "${pageContext.request.contextPath }/control/department/list_execute.action" method = "post" >              < input type = "text" name = "person.id" >< br >               < input type = "text" name = "person.name" >< br >               < input type = "submit" value = "提交" >          </ form >

   获取的值的方法如下:

   1 2	${person.id }</ br > ${person.name }

3. struts2.1.6版本存在中文请求参数乱码,可以自己添加过滤器;
