Three major framework Integration (ii)--spring and STRUTS2_ Project Environment

1, the integration of Spring and STRUTS2 purposes:
Let Spring manage instances of Action (multiple cases);

Easy injection of dependent objects.

Add Struts2-spring-plugin-2.1.8.jar, responsible for spring management object Dependency Injection

2, the integration of the steps:
Spring is used in a Web project to configure a listener to create a ApplicationContext object;
Add Struts2-spring-plugin.jar to get struts2 to take the action object from the Spring container.

3, in the Web.xml

			<!--Configure spring's listener for initializing ApplicationContext objects-->
			<listener>
				<listener-class> org.springframework.web.context.contextloaderlistener</listener-class>
			</listener>
			< context-param>
				<param-name>contextConfigLocation</param-name>
				<param-value> Classpath:applicationcontext*.xml</param-value>
			</context-param>

4, testing, in the Testaction.java

			@Controller
			public  class  testaction  extends  actionsupport{
				@Resource
				Private  testservice  testservice;

				Public  String  execute ()  throws  exception{
					s.o.p ("--------->  testservice:" + Testservice;);
					Return  "Success";
				}
			

5. Adjust Struts.xml

			<package name= "Default" namespace= "/" extends= "Struts-default" >
				<!--Configure the action for the test-->
				< Action name= "Test" class= "testaction" method= "Testservice" >
					<result name= "Success" >/test.jsp</ result>
				</action>
			</package>

Results: Access to Localhost:8080/itcastoa/test.do
If S.O.P ("---------> Testservice:" + testservice;); The testservice in is not NULL, which means success.


Above, the three major framework integration completed.

When you change only the method body, you do not need to republish. Re-publish the method name when you change it.
