Spring boot + mybatis + Vue.js + ElementUI 实现数据的增删改查实例代码(二)

在上篇文章给大家介绍了Spring boot + mybatis + Vue.js + ElementUI 实现数据的增删改查实例代码(一)，接下来我们添加分页相关的依赖，时间紧张，直接上代码了，贴上我的pom文件

接下来是yml文件，主要加入了mybatis的配置，以及sql的打印

spring:
datasource:
name: test
url: jdbc:mysql://localhost/imooc?useUnicode=true&characterEncoding=utf-8&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
mybatis:
type-aliases-package: com.imooc.model
mapper-locations: classpath:mybatis/mapper/*.xml
check-config-location: true
config-location: classpath:mybatis/mybatis-config.xml
logging:
level:
com.imooc.repository: debug
com.imooc.service.impl: debug
com.imooc.controller: debug
com.imooc.activemq: debug

接下来是repositpry文件

@Repository
public interface UserRepository {
List<User> findUsersByUsername(@Param("username") String username);
int getCount();
int saveUser(User user);
int modifyUser(User user);
int removeUser(@Param("userId") int userId);
}

service文件

@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserRepository userRepository;
@Override
public Map<String, Object> getTableData(int pageNum, int pageSize, String username) {
try {
 PageHelper.startPage(pageNum, pageSize);
 List<User> userList = userRepository.findUsersByUsername(username);
 int count = userRepository.getCount();
 Map<String, Object> tableData = new HashMap<>();
 tableData.put("list", userList);
 tableData.put("count", count);
 return tableData;
} catch (Exception e) {
 e.printStackTrace();
}
return null;
}
}
public interface UserService {
Map<String, Object> getTableData(int pageNum, int pageSize, String username);
}

controller文件

@RestController
public class UserController {
@Autowired
private UserService userService;
@GetMapping("getTableData")
public Map<String, Object> getTableData(int pageNum, int pageSize, String username) {
try {
 return userService.getTableData(pageNum, pageSize, username);
} catch (Exception e) {
 e.printStackTrace();
}
return null;
}
}

实体类

public class User {
private Integer userId;
private String username;
private Byte sex;
private Date createTime;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Byte getSex() {
return sex;
}
public void setSex(Byte sex) {
this.sex = sex;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
}

sql

CREATE TABLE `t_user` (
`user_id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(32) DEFAULT NULL,
`sex` tinyint(4) DEFAULT NULL,
`create_time` datetime DEFAULT NULL,
PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=10003 DEFAULT CHARSET=utf8

在static目录下新建 index.html文件
