Spring-Boot-2.0.0-M1版本将默认的数据库连接池从tomcat jdbc pool改为了hikari，这里主要研究下hikari的默认配置
0. 创建Spring Boot项目，选中 Web、MySQL、JDBC 依赖
1. 启动类默认加载了DataSourceAutoConfiguration，默认数据源是HikariDataSource
@SpringBootApplicationpublic class SpringBootJdbcApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootJdbcApplication.class, args);
}
}
2. 数据源配置文件属性
spring:
datasource:
url: jdbc:mysql://localhost:3306/springboot //系统自带的默认数据源配置中，用 url，若是自定义的HikariDataSource，用jdbcUrl (自定义的其它类型数据源名称取什么待测)
username: root
password: xiaochao
driver-class-name: com.mysql.cj.jdbc.Driver //老版本用com.mysql.jdbc.Driver
name: hikari
3. 测试
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootJdbcApplicationTests { @Autowired
DataSource dataSource; @Test
public void contextLoads() throws SQLException {
System.out.println(dataSource.getClass().getName());
System.out.println(dataSource.getConnection());
} }
结果：
HikariProxyConnection@265939934 wrapping com.mysql.cj.jdbc.ConnectionImpl@14982a82
com.zaxxer.hikari.HikariDataSource
4. 自定义数据源
4.1 首先排除掉系统默认数据源
-
exclude：排除，不包括，祛除，赶出，反义词 ： include
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})public class SpringBootJdbcApplication { public static void main(String[] args) {
SpringApplication.run(SpringBootJdbcApplication.class, args);
}
}
4.2 在配置类中加入自定义的线程池
@Bean
@ConfigurationProperties("spring.datasource") //此配置项名称是自定义的，只要和配置文件中的各项名称对应上就好
public HikariDataSource dataSource() {
return DataSourceBuilder.create().type(HikariDataSource.class).build();
}4.3 把配置文件中的spring.datasource.url 改为spring.datasource.jdbcUrl
- 4.4 自动以tomcat jdbc 数据源 首先引入tomcat-jdbc依赖
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
<version>9.0.13</version>
</dependency>配置tomcat数据源Bean
@Configuration
public class MyConfig { @Bean
@ConfigurationProperties("spring.datasource") //此配置项名称是自定义的，只要能和配置文件中的各项名称对应上就好
public org.apache.tomcat.jdbc.pool.DataSource dataSource() {
return DataSourceBuilder.create().type(org.apache.tomcat.jdbc.pool.DataSource.class).build();
} }
自定义其它类型的数据源方式同理
5. 数据源自动配置 源码解析

通配规则：schema‐*.sql、data‐*.sql， 优先级第三高 eg：schema-emp.sql, schema-dept.sql； data-emp.sql ，data-dept.sql
默认规则：schema.sql，schema‐all.sql (或者关系，给用户多个选择)； 优先级第二高，
自定义规则：yml中配置，根据上面代码，优先级高
spring:
datasource:
schema:
‐ classpath: department.sql
‐ classpath: user.sql
......
data:
‐ classpath: department_initData.sql
‐ classpath: user_initData.sql
......
自定义指定的SQL文件
经过测验，schema.sql 和schema-all.sql 在resources目录下并没有生效，有待继续查验
6. jdbcTemplate操作数据库
@Controller
@RequestMapping("/user")
public class UserController { @Autowired
JdbcTemplate jdbcTemplate; @ResponseBody
@RequestMapping("/getById2/{id}")
public List<Map<String, Object>> selectByPrimaryKey2(@PathVariable Integer id){
//这种query is OK
List<Map<String, Object>> maps = jdbcTemplate.queryForList("SELECT * FROM USER");
return maps; //以下几种方式都会产生error,error信息见下文：待查明
// Object[] obj = new Object[1];
// obj[0] = id;
// return jdbcTemplate.queryForList("select * from user where id = ?", obj,User.class);
// return jdbcTemplate.queryForList("SELECT * FROM USER", User.class);
// return jdbcTemplate.queryForObject("select id,name,sex,age from user where id = " + id,User.class);
}
