spring和spring MVC整合

标签：spring mvc   spring   

spring和springMVC之间的整合，springMVC中的jar包包含spring中的jar包，所以无需再另外导入jar包，只需导入springMVC的jar包即可。

如图一所示:

这个时候，再新建两个源文件夹，一个为config专门放配置文件，另外一个为test，专门用来放进行测试的程序，在这个整合的小项目中，本身

并没有用上test源文件夹，但是加上倒也不错。

现在，在config文件夹中新建两个xml文件，一个为spring的配置文件，为applicationContext.xml,另一个为springmvc 的配置文件为springmvc.xml,两个xml

文件的配置如下：

applicationContext.xml:

下面依次为各个程序的代码：

ISpring:

package cn.com.controller;

public interface ISpring {
	void get();
}

package cn.com.controller;

public class SpringManager implements ISpring {

	public void get() {
		System.out.println("spring和spring mvc整合成功！");
	}
	
}

package cn.com.controller;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.springframework.web.servlet.support.RequestContextUtils;


@Controller
@RequestMapping("/user")
public class UserController {

	@Resource(name="springManager")
	
	private ISpring springManager;
	@RequestMapping("/toSuccess.do")
	public String ToSuccess(HttpServletRequest request){
		//spring上下文
		WebApplicationContext ac1 = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());
		//springmvc的上下文
		WebApplicationContext ac2=RequestContextUtils.getWebApplicationContext(request);
		springManager.get();
		return "success";
	}
}

debug调试观察ac1与ac2：

如下图所示：

spring上下文：

springmvc上下文：

jsp页面为：

如此，spring和springmvc的整合就成功了。
