一个完整的项目流程
1：运行数据库脚本
2：导项目
3：修改maven地址
4：运行现在依赖
5：改application.yml(数据库名，密码)
6：改jdbc.properties((数据库名，密码)
7:generatorConfig.xml (改成自己mysql依赖的位置 )
8.运行项目是否报错
9：生成代码
10：mapper类加注解 @Repository
加注释/**/
干掉id的
11：复制xxxmapper改成xxxmapper,吧s改为大写，保留所需要的方法，其他的删除，一定要删掉注解@Repository12：实现接口，放到方法名上alt+回车，下面叫impl,一定要加service注解
13：创建BookController接口，加注释@RestController
@RequestMapping("/book").........
1：建数据库建表
create table t_student(
sid int not null auto_increment primary key comment '学生编号',
sname varchar(50) not null comment '学生姓名',
score float default 0 comment '书本价格',
sex varchar(20) comment '学生性别'
) comment '学生成绩表';
insert into t_student(sname,score,sex) values
('张三',90,'男'),
('李四',120,'女'),
('王五',60,'男')
2：导项目
3：修改maven地址
5：改application.yml(数据库名，密码)
6：改jdbc.properties((数据库名，密码)
7:generatorConfig.xml (改成自己mysql依赖的位置 )
8.运行项目是否报错
9：生成代码
10：mapper类加注解 @Repository
加注释/**/

11：复制xxxmapper改成xxxmapper,吧s改为大写，保留所需要的方法，其他的删除，一定要删掉注解@Repository
12：实现接口，放到方法名上alt+回车，下面叫impl,一定要加service注解
@Service
public class StudentServiceImpl implements StudentService {
@Autowired
private StudentMapper studentMapper;
@Override
public List<Student> query(Student student) {
return studentMapper.query(student);
}
@Override
public int insert(Student record) {
return studentMapper.insert(record);
}
}
13：创建BookController接口，加注释@RestController
@RequestMapping("/book").........
@RestController @RequestMapping("/student") public class StudentContorller { @Autowired private StudentService studentService; /** * 根据学生模糊查询 * @param student * @return */ @RequestMapping("/query") public JsonResponseBody<?> query(Student student){ List<Student> list= studentService.query(student); return new JsonResponseBody<>(200,"OK",list); } /** * 根据学生新增 * @param student * @return */ @RequestMapping("/add") public JsonResponseBody<?> add(Student student){ studentService.insert(student); return new JsonResponseBody<>(); } @Data @AllArgsConstructor @NoArgsConstructor class JsonResponseBody<T>{ private int code=200; private String msg="OK"; private T data; } }
运行一下看有没有错比如运行http://localhost:8080/spboot/book/query
//配置好所定义的接口
'ADD':'/student/add',
'QUERY':'/student/query',
//写页面

<!--2.数据表格 -->
