SSH三大框架注解整合(一)
1.导入jar包,ssh的jar包一共是38个,此时还需要多加一个包,就是struts的注解插件jar。
2.在web.xml文件中配置struts filter 和spring 的listener。代码如下:
<!-- spring 监听器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
3.编写jsp页面
<s:form action="addBook" namespace="/" method="post" theme="simple">
书名 <s:textfield name="name"/> <br/>
作者 <s:textfield name="author" /> <br/>
<s:submit value="添加图书"></s:submit>
</s:form>
4.利用struts注解编写action
@ParentPackage(value = "struts-default")
@Namespace("/")
public class BookAction extends ActionSupport implements ModelDriven<Book>{
//模型驱动
public Book book = new Book();
public void setBook(Book book) {
this.book = book;
}
@Override
public Book getModel() {
return book;
}
@Override
@Action(value="addBook",results={@Result(name="success",location="/success.jsp")})
public String execute() throws Exception {
return SUCCESS;
}
}
