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
<!--集成mysql数据库--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency>
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
// // Source code recreated from a .class file by IntelliJ IDEA // (powered by Fernflower decompiler) // package org.springframework.boot.autoconfigure.jdbc; import com.zaxxer.hikari.HikariDataSource; import javax.sql.DataSource; import org.apache.commons.dbcp2.BasicDataSource; import org.springframework.boot.autoconfigure.condition.ConditionalOnClass; import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean; import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.jdbc.DatabaseDriver; import org.springframework.context.annotation.Bean; import org.springframework.util.StringUtils; abstract class DataSourceConfiguration { DataSourceConfiguration() { } protected static <T> T createDataSource(DataSourceProperties properties, Class<? extends DataSource> type) { return properties.initializeDataSourceBuilder().type(type).build(); } @ConditionalOnMissingBean({DataSource.class}) @ConditionalOnProperty( name = {"spring.datasource.type"} ) static class Generic { Generic() { } @Bean public DataSource dataSource(DataSourceProperties properties) { return properties.initializeDataSourceBuilder().build(); } } @ConditionalOnClass({BasicDataSource.class}) @ConditionalOnMissingBean({DataSource.class}) @ConditionalOnProperty( name = {"spring.datasource.type"}, havingValue = "org.apache.commons.dbcp2.BasicDataSource", matchIfMissing = true ) static class Dbcp2 { Dbcp2() { } @Bean @ConfigurationProperties( prefix = "spring.datasource.dbcp2" ) public BasicDataSource dataSource(DataSourceProperties properties) { return (BasicDataSource)DataSourceConfiguration.createDataSource(properties, BasicDataSource.class); } } @ConditionalOnClass({HikariDataSource.class}) @ConditionalOnMissingBean({DataSource.class}) @ConditionalOnProperty( name = {"spring.datasource.type"}, havingValue = "com.zaxxer.hikari.HikariDataSource", matchIfMissing = true ) static class Hikari { Hikari() { } @Bean @ConfigurationProperties( prefix = "spring.datasource.hikari" ) public HikariDataSource dataSource(DataSourceProperties properties) { HikariDataSource dataSource = (HikariDataSource)DataSourceConfiguration.createDataSource(properties, HikariDataSource.class); if (StringUtils.hasText(properties.getName())) { dataSource.setPoolName(properties.getName()); } return dataSource; } } @ConditionalOnClass({org.apache.tomcat.jdbc.pool.DataSource.class}) @ConditionalOnMissingBean({DataSource.class}) @ConditionalOnProperty( name = {"spring.datasource.type"}, havingValue = "org.apache.tomcat.jdbc.pool.DataSource", matchIfMissing = true ) static class Tomcat { Tomcat() { } @Bean @ConfigurationProperties( prefix = "spring.datasource.tomcat" ) public org.apache.tomcat.jdbc.pool.DataSource dataSource(DataSourceProperties properties) { org.apache.tomcat.jdbc.pool.DataSource dataSource = (org.apache.tomcat.jdbc.pool.DataSource)DataSourceConfiguration.createDataSource(properties, org.apache.tomcat.jdbc.pool.DataSource.class); DatabaseDriver databaseDriver = DatabaseDriver.fromJdbcUrl(properties.determineUrl()); String validationQuery = databaseDriver.getValidationQuery(); if (validationQuery != null) { dataSource.setTestOnBorrow(true); dataSource.setValidationQuery(validationQuery); } return dataSource; } } }

package org.springframework.boot.autoconfigure.jdbc; import ......; class DataSourceInitializer { //【初始化程序】 private static final Log logger = LogFactory.getLog(DataSourceInitializer.class); private final DataSource dataSource; private final DataSourceProperties properties; private final ResourceLoader resourceLoader; DataSourceInitializer(DataSource dataSource, DataSourceProperties properties, ResourceLoader resourceLoader) { this.dataSource = dataSource; this.properties = properties; this.resourceLoader = (ResourceLoader)(resourceLoader != null ? resourceLoader : new DefaultResourceLoader()); } DataSourceInitializer(DataSource dataSource, DataSourceProperties properties) { this(dataSource, properties, (ResourceLoader)null); } public DataSource getDataSource() { return this.dataSource; } //建表SQL,classpath*:schema-*.sql public boolean createSchema() {

//这里为啥add（） 2个 SQL？ fallbackResources.add("classpath*:" + fallback + "-" + platform + ".sql"); //DatasourceProperties中的构造器中，platform默认被赋值为 all fallbackResources.add("classpath*:" + fallback + ".sql"); return this.getResources(propertyName, fallbackResources, false); } } 。。。。。。 //运行SQL脚本 private void runScripts(List<Resource> resources, String username, String password) { if (!resources.isEmpty()) { ResourceDatabasePopulator populator = new ResourceDatabasePopulator(); populator.setContinueOnError(this.properties.isContinueOnError()); populator.setSeparator(this.properties.getSeparator()); if (this.properties.getSqlScriptEncoding() != null) { populator.setSqlScriptEncoding(this.properties.getSqlScriptEncoding().name()); } Iterator var5 = resources.iterator(); while(var5.hasNext()) { Resource resource = (Resource)var5.next(); populator.addScript(resource); } DataSource dataSource = this.dataSource; if (StringUtils.hasText(username) && StringUtils.hasText(password)) { dataSource = DataSourceBuilder.create(this.properties.getClassLoader()).driverClassName(this.properties.determineDriverClassName()).url(this.properties.determineUrl()).username(username).password(password).build(); } DatabasePopulatorUtils.execute(populator, dataSource); } } }

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); } }
