maven+ssm项目整合之分页

一，在pom.xml配置插件

maven+ssm项目整合之分页

<dependency>
        <groupId>com.github.pagehelper</groupId>
        <artifactId>pagehelper</artifactId>
        <version>5.0.0</version>
       </dependency>

二，在mybaitis的配置里

在application.xml里面（上图）可以知道mybatis的全局配置是mybatis-config.xml

三.controller的代码

四.使用test去测试分页功能时

package com.atguigu.crud.test;

import java.util.List;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import com.atguigu.crud.bean.Employee;
import com.github.pagehelper.PageInfo;

/**
* 使用Spring测试模块提供的测试请求功能，测试curd请求的正确性
* Spring4测试的时候，需要servlet3.0的支持
* @author lfy
*
*/
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = { "classpath:applicationContext.xml",
       "file:src/main/webapp/WEB-INF/dispatcherServlet-servlet.xml" })
public class MvcTest {
   // 传入Springmvc的ioc
   @Autowired
   WebApplicationContext context;
   // 虚拟mvc请求，获取到处理结果。
   MockMvc mockMvc;

   @Before
   public void initMokcMvc() {
       mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
   }

   @Test
   public void testPage() throws Exception {
       //模拟请求拿到返回值
       MvcResult result = mockMvc.perform(MockMvcRequestBuilders.get("/emps").param("pn", "5"))
               .andReturn();

       //请求成功以后，请求域中会有pageInfo；我们可以取出pageInfo进行验证
       MockHttpServletRequest request = result.getRequest();
       PageInfo pi = (PageInfo) request.getAttribute("pageInfo");
       System.out.println("当前页码："+pi.getPageNum());
       System.out.println("总页码："+pi.getPages());
       System.out.println("总记录数："+pi.getTotal());
       System.out.println("在页面需要连续显示的页码");
       int[] nums = pi.getNavigatepageNums();
       for (int i : nums) {
           System.out.print(" "+i);
       }

       //获取员工数据
       List<Employee> list = pi.getList();
       for (Employee employee : list) {
           System.out.println("ID："+employee.getEmpId()+"==>Name:"+employee.getEmpName());
       }

   }

}
