SSM框架的(CRUD)查询_使用Spring单元测试测试分页请

1、test文件夹新建MvcTest.java类进行测试

/**
 * 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

@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());
        }
    }
