今天完成的事情：

重新写SSM

controller

@Controller
@RequestMapping("/student")
public class HelloWorldController {
    @Autowired
    StudentService studentService;
    private static final Logger log = LogManager.getLogger(HelloWorldController.class);

    /**
     * 跳转到学生添加界面
     */
    @RequestMapping(value = "/toAddStudent")
    public String toAddStudent() {
        return "addStudent";
    }

    /**
     * 添加学生
     */

    @RequestMapping("addStudent")
    public String addStudent( Model model, Student student) {
        if (student != null) {
            studentService.insertStudent(student);
        }
        return "redirect:/student/findAllStudent";
    }

/**
 * 查询学生所有数据
 */
@RequestMapping(value = "findAllStudent" ,method = RequestMethod.GET)
public String findAllStudent(Model model,@RequestParam(defaultValue = "1",required = true,
        value = "pageNo") Integer pageNo) {
    //每页显示记录数为5
    Integer pageSize=5;
    PageHelper.startPage(pageNo,pageSize);
    List<Student> students = studentService.findAllStudent();
    PageInfo<Student> pageInfo =new PageInfo<Student>(students);
    model.addAttribute("pageInfo", pageInfo);
    return "allStudent";
}

这个页面不知道为啥报红

点进入学生管理界面不知道为什么出现500

报错信息：

org.springframework.web.servlet.FrameworkServlet.initServletBean Context initialization failed

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 64 in XML document from file [D:\task2_c\target\task2_c\WEB-INF\classes\spring\spring-applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 64; columnNumber: 70; 元素 "tx:annotation-driven" 的前缀 "tx" 未绑定。

明天计划的事情：把这个几个BUG解决了 再测试接口
收获：熟悉SSM的配置
