5.Spring和Mybatis测试

　　5.1 测试分为两种(1.使用junit测试   2.编写测试类)

　　　　我用的是编写测试类测试　　　　

1 package com.vivebest.test; 2  3 import org.springframework.context.ApplicationContext; 4 import org.springframework.context.support.ClassPathXmlApplicationContext; 5 import com.vivebest.service.CustomerService; 6  7 public class Test { 8     private ApplicationContext ac = null;  9     public static void main(String[] args) {10         Test test=new Test();11         test.before();12     }13     public void before() {  14       ac = new ClassPathXmlApplicationContext("applicationContext.xml"); //引入配置文件 15       CustomerService customerService= (CustomerService) ac.getBean("customerService");//需要注意这里的customerService 是在service中使用@Service（“customerService”）一致16       System.out.println(customerService.getAllCustomer());17     /*  CustomerService TellerService= (CustomerService) ac.getBean("TellerService");18       System.out.println(TellerService);*/19   } 20 }

6.SSM整合测试

　　编写controller层

1 package com.vivebest.controller; 2  3 import java.util.List; 4 import javax.servlet.http.HttpServletRequest; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.stereotype.Controller; 7 import org.springframework.ui.Model; 8 import org.springframework.web.bind.annotation.RequestMapping; 9 import org.springframework.web.bind.annotation.RequestMethod;10 import org.springframework.web.bind.annotation.ResponseBody;11 import com.vivebest.entity.Customer;12 import com.vivebest.service.CustomerService;13 14 15 @Controller//标明为控制层16 @RequestMapping("/customer")//相当于路径17 public class CustomerController{18 19     @Autowired20     private CustomerService customerService;21     22     /**23      * 客户登陆24      */25     @RequestMapping(value ="/customerLogin", method = RequestMethod.POST)26     public String customerLogin(Model model,HttpServletRequest req){27         List
     
       cusList=customerService.getAllCustomer();28         Customer custom=cusList.get(0);29         req.setAttribute("custome", custom);30         System.out.println(custom);31         return "finally";32     }33 }
     

编写jsp页面，在jsp页面中我遇到了一个小问题，即 

 在使用jstl.jar中 因为

"org.apache.jasper.JasperException: This absolute uri ( ) cannot be resolved in either web.xml or the jar files deployed with this application "

    由于JSTL1.0和JSTL1.1的声明语句不一样。

这个问题在另一边文章中我做了总结，大家可以去游览。

启动工程，测试成功！
