2.添加配置
在application.yml文件中添加如下配置信息
server:
port: 8080
spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
click:
driverClassName: ru.yandex.clickhouse.ClickHouseDriver
url: jdbc:clickhouse://172.16.100.17:8123/esthihiate
initialSize: 10
maxActive: 100
minIdle: 10
maxWait: 6000
mybatis-plus:
configuration:
call-setters-on-nulls: true
auto-mapping-behavior: full
map-underscore-to-camel-case: true
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
mapper-locations: com.springbootdemo.dao.mapper.*Mapper.xml
logging:
file:
name: springbootdemo.log添加数据源配置
package com.springbootdemo.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
/**
* JdbcParamConfig
*
* @Description
*/
@Configuration
@Data
@ConfigurationProperties(prefix = "spring.datasource.click")
public class JdbcParamConfig {
private String driverClassName;
private String url;
private Integer initialSize;
private Integer maxActive;
private Integer minIdle;
private Integer maxWait;
}
package com.springbootdemo.config;
import com.alibaba.druid.pool.DruidDataSource;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import javax.annotation.Resource;
import javax.sql.DataSource;
/**
* DataSourceClickHouseConfig
*
* @Description
*/
@Configuration
public class DruidDataSourceConfig {
@Resource
private JdbcParamConfig jdbcParamConfig;
@Bean
public DataSource dataSource(){
DruidDataSource dataSource = new DruidDataSource();
dataSource.setUrl(jdbcParamConfig.getUrl());
dataSource.setDriverClassName(jdbcParamConfig.getDriverClassName());
dataSource.setInitialSize(jdbcParamConfig.getInitialSize());
dataSource.setMinIdle(jdbcParamConfig.getMinIdle());
dataSource.setMaxActive(jdbcParamConfig.getMaxActive());
dataSource.setMaxWait(jdbcParamConfig.getMaxWait());
return dataSource;
}
}
添加mybatisplus插件
package com.springbootdemo.config;
import com.baomidou.mybatisplus.extension.plugins.OptimisticLockerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**
* MybatisPlusConfig
*
* @Description
*/
@Configuration
@EnableTransactionManagement
@MapperScan("com.springbootdemo.dao.mapper")
public class MybatisPlusConfig {
/**
* 配置乐观锁插件
* @return
*/
@Bean
public OptimisticLockerInterceptor optimisticLockerInterceptor() {
return new OptimisticLockerInterceptor();
}
/**
* 分页插件
* @return
*/
@Bean
public PaginationInterceptor paginationInterceptor(){
return new PaginationInterceptor();
}
}
3.entity类
package com.springbootdemo.entity;
import com.alibaba.druid.support.monitor.annotation.MTable;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;
/**
* UserInfo
*
* @Description
*/
@Data
@TableName("cs_user_info")
public class UserInfo {
@TableId("id")
private Long id;
private String userName;
private String passWord;
private String phone;
private String email;
private String createDay;
}
4.dao层
package com.springbootdemo.dao;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.springbootdemo.entity.UserInfo;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
/**
* UserInfoMapper
*
* @Description
*/
@Repository
public interface UserInfoMapper extends BaseMapper {
Long selectMaxId();
}
5.mapper层
6.service层
package com.springbootdemo.service;
import com.baomidou.mybatisplus.core.conditions.Wrapper;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.core.conditions.update.UpdateWrapper;
import com.springbootdemo.dao.UserInfoMapper;
import com.springbootdemo.entity.UserInfo;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
/**
* UserInfoService
*
* @Description
*/
@Service
public class UserInfoService {
@Resource
private UserInfoMapper userInfoMapper;
public void saveData(UserInfo userInfo) {
//userInfo.setId(userInfoMapper.selectMaxId()+1);
userInfoMapper.insert(userInfo);
}
public UserInfo selectById(@Param("id") Integer id) {
return userInfoMapper.selectById(id);
}
public List selectList() {
QueryWrapper queryWrapper = new QueryWrapper<>();
return userInfoMapper.selectList(queryWrapper);
}
}
7.controller层
package com.springbootdemo.controller;
import com.alibaba.fastjson.JSON;
import com.springbootdemo.entity.UserInfo;
import com.springbootdemo.service.UserInfoService;
import org.apache.ibatis.annotations.Param;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
import java.util.List;
/**
* UserInfoController
*
* @Description
*/
@RestController
@RequestMapping("/api/userInfo")
public class UserInfoController {
@Resource
private UserInfoService userInfoService;
@RequestMapping("/saveData")
public void saveData(){
UserInfo userInfo = new UserInfo();
userInfo.setId(1L);
userInfo.setCreateDay("2022-04-15");
userInfo.setEmail("[email protected]");
userInfo.setPhone("13243545464");
userInfo.setUserName("admin");
userInfo.setPassWord("admin");
userInfoService.saveData(userInfo);
}
@RequestMapping("/selectById")
public String selectById(@Param("id") Integer id){
return JSON.toJSONString(userInfoService.selectById(id));
}
@RequestMapping("/selectList")
public String selectList(){
return JSON.toJSONString(userInfoService.selectList());
}
}
