2. 创建数据库user表

CREATE TABLE `t_sys_user` (
  `id` char(36) NOT NULL,
  `username` varchar(255) DEFAULT NULL,
  `password` varchar(255) DEFAULT NULL,
  `email` varchar(255) DEFAULT NULL,
  `mobile` varchar(11) DEFAULT NULL,
  `login_ip` varchar(255) DEFAULT NULL,
  `login_time` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
  `is_aviliable` tinyint(4) DEFAULT NULL,
  `type` int(2) DEFAULT NULL,
  `avatar` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `username` (`username`) USING HASH,
  KEY `email` (`email`),
  KEY `mobile` (`mobile`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

不需要的字段可以酌情删除，实际上可以只保留username和password字段

3. 创建generatorConfig.xml 用于自动生成mapper文件和模型

运行一下插件就可以生成代码了

4. 加入启动类

package com.itcuc.qaserver;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@SpringBootApplication
@MapperScan("com.itcuc.qaserver.mapper")
public class QaserverApplication {

    public static void main(String[] args) {
        SpringApplication.run(QaserverApplication.class, args);
    }
}

5. 配置application.properties

server.port=8080

spring.datasource.name=qadata
spring.datasource.url=jdbc:mysql://localhost:3306/qa
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.type=com.mchange.v2.c3p0.ComboPooledDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
spring.datasource.minIdle=1
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=select 'x'
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
spring.datasource.poolPreparedStatements=100
spring.datasource.maxOpenPreparedStatements=20

mybatis.type-aliases-package=com.itcuc.qaserver.model
mybatis.mapper-locations=classpath:mapping/*.xml

6. 创建DataSource和Sessionfactory

DataSourceConfiguration 类配置c3p0数据源
SessionFactoryConfiguration 类配置SqlSessionFactory

@SpringBootConfiguration
public class DataSourceConfiguration {
    @Value("${spring.datasource.driver-class-name}")
    private String jdbcDriver;
    @Value("${spring.datasource.url}")
    private String jdbcUrl;
    @Value("${spring.datasource.username}")
    private String jdbcUser;
    @Value("${spring.datasource.password}")
    private String jdbcPassword;
    @Value("${spring.datasource.maxActive}")
    private Integer maxPoolSize;
    @Value("${spring.datasource.maxWait}")
    private Integer maxIdleTime;
    @Value("${spring.datasource.minIdle}")
    private Integer minPoolSize;
    @Value("${spring.datasource.poolPreparedStatements}")
    private Integer maxStatements;
    @Value("${spring.datasource.timeBetweenEvictionRunsMillis}")
    private Integer idleConnectionTestPeriod;
    @Value("${spring.datasource.validationQuery}")
    private String preferredTestQuery;
    @Value("${spring.datasource.testOnBorrow}")
    private Boolean testConnectionOnCheckin;
    @Value("${spring.datasource.testOnReturn}")
    private Boolean testConnectionOnCheckout;
    @Bean
    public DataSource createDataSource() throws PropertyVetoException {
        ComboPooledDataSource dataSource = new ComboPooledDataSource();

        dataSource.setDriverClass(jdbcDriver);
        dataSource.setJdbcUrl(jdbcUrl);
        dataSource.setUser(jdbcUser);
        dataSource.setPassword(jdbcPassword);
        dataSource.setMaxPoolSize(maxPoolSize);
        dataSource.setMaxIdleTime(maxIdleTime);
        dataSource.setMinPoolSize(minPoolSize);
        dataSource.setMaxStatementsPerConnection(maxStatements);
        dataSource.setIdleConnectionTestPeriod(idleConnectionTestPeriod);
        dataSource.setPreferredTestQuery(preferredTestQuery);
        dataSource.setTestConnectionOnCheckin(testConnectionOnCheckin);
        dataSource.setTestConnectionOnCheckout(testConnectionOnCheckout);
        dataSource.setAutoCommitOnClose(false);

        return dataSource;
    }
}

@SpringBootConfiguration
public class SessionFactoryConfiguration {

    @Value("${mybatis.mapper-locations}")
    private String mapperXMLConfigPath;
    @Value("${mybatis.type-aliases-package}")
    private String mapperPackagePath;
    @Autowired
    private DataSource dataSource;

    @Bean
    public SqlSessionFactoryBean createSqlSessionFactory() throws IOException {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        String packageXMLConfigPath = mapperXMLConfigPath;

        // 设置mapper 对应的XML 文件的路径
        sqlSessionFactoryBean.setMapperLocations(resolver.getResources(packageXMLConfigPath));
        // 设置数据源
        sqlSessionFactoryBean.setDataSource(dataSource);
        // 设置mapper 接口所在的包
        sqlSessionFactoryBean.setTypeAliasesPackage(mapperPackagePath);

        return sqlSessionFactoryBean;
    }
}

7. 创建一个简单的api

@RestController
@RequestMapping("/api/index")
public class IndexController {
    @GetMapping("hello")
    public String hello() {
        return "hello";
    }
}

使用crap测试接口
