Spring Struts Integration

The Spring framework provides a simple method for managing dependencies. It can easily be integrated with struts 2Framework integration.

ContextLoaderListener Class for communication with Struts 2Communication with the Spring application. It must be specified in the web.xml file.

You need to perform the following steps:

Create struts2Application and add the spring jar file. In web.xml Define the ContextLoaderListener class in the file. In struts.xml Define the bean name for the action class in the file. In applicationContext.xml Create a Bean in the file. The class name should be the action class name, such as com.w3codebox.Login and id should match the action class (e.g., login) in the struts.xml file. In Action ClassDefine other properties, such as messages, in

Spring and Struts 2Integration Example

You need to create the following files to simplify the operation of spring and struts 2Application:

index.jsp web.xml struts.xml applicationContext.xml Login.java welcome.jsp error.jsp

1)index.jsp

This page retrieves the name from the user.

Example

<%@　taglib　uri="/struts-tags"　prefix="s"%>
<s:form action="login">
<s:textfield name="userName" label="UserName"></s:textfield>
<s:submit></s:submit>
</s:form>

2)web.xml

it provides for struts 2and ContextLoaderListener The listener class defines the controller class to be used in struts2Establish a connection between the application and the spring application.

Example

<?xml version="1.0" encoding="UTF-8"?>
<web-app　version="2.5"　
　　xmlns="http://java.sun.com/xml/ns/javaee"　
　　xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance　
　　xsi:schemaLocation="http://java.sun.com/xml/ns/javaee　
　　http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
　　<welcome-file-list>
　　　　<welcome-file>index.jsp</welcome-file>
　　</welcome-file-list>
　　<filter>
　　　　<filter-name>struts2</filter-name
　　　　<filter-class
　　　　　　org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
　　　　</filter-class
　　</filter>
　　
<listener>　
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class　
</listener　
　　
　　<filter-mapping>
　　　　<filter-name>struts2</filter-name
　　　　<url-pattern>/*</url-pattern>
　　</filter-mapping>
　　
　　</web-app>

3)struts.xml

It defines a package containing operations and results. Here, the action class name is login, which will be searched in the applicationContext.xml file.

Example

<?xml version="1.0" encoding="UTF-8"　?>
<!DOCTYPE struts public "-//Apache Software Foundation//DTD Struts Configuration　2.1//EN　
"http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="abc" extends="struts-default">
<action name="login" class="login">
<result name="success">welcome.jsp</result>
</action>
</package>
</struts>

4)applicationContext.xml

It defines a bean with the ID login name. The bean corresponds to the mypack.Login class.

It should be located in the WEB-INF directory.

Example

<?xml version="1.0" encoding="UTF-8"?>
<beans
　　xmlns="http://www.springframework.org/schema/beans
　　xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
　　xmlns:p="http://www.springframework.org/schema/p
　　xsi:schemaLocation="http://www.springframework.org/schema/beans　
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="login" class="mypack.Login">
<property name="message" value="Welcome Spring"></property>
</bean>
</beans>

5Login.java

It defines two properties userName and a message with an execute method that returns success.

Example

package　mypack;
public　class　Login　{
private　String　userName,message;
public　String　getMessage()　{
　　return　message;
}
public　void　setMessage(String　message)　{
　　this.message　=　message;
}
public　String　getUserName()　{
　　return　userName;
}
public　void　setUserName(String　userName)　{
　　this.userName　=　userName;
}
public　String　execute(){
　　return　"success";
}
}

6)welcome.jsp

It displays the values of the userName and message properties.

Example

<%@　taglib　uri="/struts-tags"　prefix="s"%>
Welcome,　<s:property　value="userName"/><br/>
${message}

7)error.jsp

This is an error page. But it is not necessary, because we have not defined any logic in the execute method of the action class.

Example

Sorry!
