amework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
public class StudentServiceImpl implements IStudentService {
@Autowired
private StudentMapper studentMapper;
@Override
public List<StudentEntity> selectAll() {
return studentMapper.selectAll();
}
@Transactional
@Override
public int save(StudentEntity studentEntity) {
return 0;
}
}
8.创建Controller
package com.bdqn.lyrk.ssm.study.controller;
import com.bdqn.lyrk.ssm.study.entity.StudentEntity;
import com.bdqn.lyrk.ssm.study.service.IStudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.List;
@Controller
public class IndexController {
@Autowired
private IStudentService studentService;
@GetMapping("/index")
public String index(ModelMap modelMap) {
List<StudentEntity> list = studentService.selectAll();
modelMap.put("students", list);
return "index";
}
}

10.启动tomcat后访问http://localhost:8080/portal/index得到如下界面
OK！大功告成，注意前4步里面注解的运用，后面的步骤和往常的写法无异，想必大家都很熟悉了吧。
