JFinal框架也整合了Spring框架，下面实现JFinal怎么去配置Spring框架。在JFinal中整合Spring使用到的类是SpringPlugin和IocInterceptor类

SpringIplugin类：

SpringPlugin 是作为 JFinal 的 Plugin 而存在的，所以使用时需要在 JFinalConfig 中配置SpringPlugin，以下是 Plugin 配置示例代码：

@Override
	public void configPlugin(Plugins me) {

<span style="white-space:pre">		</span>//配置Spring挂件
		me.add(new SpringPlugin());
	}

以前学习Spring养成了习惯将Spring的配置放在src下，这里我还是放在src的spring包中，如下：

@Override
	public void configPlugin(Plugins me) {
		//配置Spring挂件， 自动找spring包中所有的xml配置文件
		me.add(new SpringPlugin("classpath*:spring/*.xml"));
	}

package com.tenghu.core.controller;

import java.util.List;

import com.jfinal.aop.Before;
import com.jfinal.core.Controller;
import com.jfinal.plugin.spring.Inject;
import com.jfinal.plugin.spring.IocInterceptor;
import com.tenghu.core.model.Users;
import com.tenghu.core.service.LoginService;
import com.tenghu.core.validator.LoginValidator;

@Before(IocInterceptor.class)
public class IndexController extends Controller{
	@Inject.BY_NAME
	private LoginService loginService;
	public void index(){
		List<Users> testList=Users.dao.find("select * from users");
		setAttr("testList", testList);
		render("login.html");
	}
	
	public void login(){
		String username=getPara("name");
		String password=getPara("password");
		if(loginService.login(username, password)){
			renderText("登录成功");
		}else{
			renderText("登录失败");
		}
	}
}

登录服务接口与实现类：

package com.tenghu.core.service;

public interface LoginService {
	/**
	 * 登录处理
	 */
	public boolean login(String username,String password);
}

package com.tenghu.core.service.impl;

import com.tenghu.core.service.LoginService;

public class LoginServiceImpl implements LoginService{
	/**
	 * 登录处理
	 */
	public boolean login(String username, String password) {
		if("admin".equals(username)&&"admin".equals(password)){
			return true;
		}
		return false;
	}
}
