配置完成，编写代码测试

pojo

package cn.scitc.test.pojo;

import java.util.Date;

public class Student {
    private Integer id;
    private String name;
    private Date birthday;

    public Integer getId() {

        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }
}

StudentMapper

public interface StudentMapper {
    List<Student> queryStudentAll();
}

StudentMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>

    </select>
</mapper>

StudentService

public interface StudentService {
    List<Student> queryStudentAll();
}

StudentServiceImpl

@Service
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentMapper studentMapper;

    @Override
    public List<Student> queryStudentAll() {
        return studentMapper.queryStudentAll();
    }
}

StudentController

@Controller
@RequestMapping("/student")
public class StudentController {

    @Autowired
    private StudentService studentService;

    @RequestMapping("/query")
    public String query(Model model) {
        List<Student> studentList =  studentService.queryStudentAll();
        model.addAttribute("studentList",studentList);
        return "test";
    }
}

jsp页面显示

<body>
<table border="1">
    <tr>
        <td>id</td>
        <td>name</td>
        <td>birthday</td>
    </tr>

注意导入的标签库为：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt_rt" %>  //fmt会报错
