Spring-Boot-2.0.0-M1版本將默認的數據庫連接池從tomcat jdbc pool改為了hikari，這里主要研究下hikari的默認配置
0. 創建Spring Boot項目，選中 Web、MySQL、JDBC 依賴
1. 啟動類默認加載了DataSourceAutoConfiguration，默認數據源是HikariDataSource
@SpringBootApplicationpublic class SpringBootJdbcApplication { public static void main(String[] args) { SpringApplication.run(SpringBootJdbcApplication.class, args); } }
2. 數據源配置文件屬性
spring: datasource: url: jdbc:mysql://localhost:3306/springboot //系統自帶的默認數據源配置中，用 url，若是自定義的HikariDataSource，用jdbcUrl (自定義的其它類型數據源名稱取什么待測) username: root password: xiaochao driver-class-name: com.mysql.cj.jdbc.Driver //老版本用com.mysql.jdbc.Driver name: hikari
3. 測試
@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()); } }
結果：
HikariProxyConnection@265939934 wrapping com.mysql.cj.jdbc.ConnectionImpl@14982a82
com.zaxxer.hikari.HikariDataSource
4. 自定義數據源
4.1 首先排除掉系統默認數據源
- exclude：排除，不包括，祛除，趕出，反義詞 ： include
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})public class SpringBootJdbcApplication { public static void main(String[] args) { SpringApplication.run(SpringBootJdbcApplication.class, args); } }
4.2 在配置類中加入自定義的線程池
-
@Bean @ConfigurationProperties("spring.datasource") //此配置項名稱是自定義的，只要和配置文件中的各項名稱對應上就好 public HikariDataSource dataSource() { return DataSourceBuilder.create().type(HikariDataSource.class).build(); }
-
4.3 把配置文件中的spring.datasource.url 改為spring.datasource.jdbcUrl
- 4.4 自動以tomcat jdbc 數據源 首先引入tomcat-jdbc依賴
-
<dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-jdbc</artifactId> <version>9.0.13</version> </dependency>
-
配置tomcat數據源Bean
@Configuration public class MyConfig { @Bean @ConfigurationProperties("spring.datasource") //此配置項名稱是自定義的，只要能和配置文件中的各項名稱對應上就好 public org.apache.tomcat.jdbc.pool.DataSource dataSource() { return DataSourceBuilder.create().type(org.apache.tomcat.jdbc.pool.DataSource.class).build(); } }
自定義其它類型的數據源方式同理
5. 數據源自動配置 源碼解析
// // 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; } } }
參考文檔：Spring Boot 官方文檔 —— 84.1 Configure a Custom DataSource 章節
package org.springframework.boot.autoconfigure.jdbc; @Configuration @ConditionalOnClass({DataSource.class, EmbeddedDatabaseType.class}) @EnableConfigurationProperties({DataSourceProperties.class}) @Import({DataSourcePoolMetadataProvidersConfiguration.class, DataSourceInitializationConfiguration.class}) public class DataSourceAutoConfiguration { public DataSourceAutoConfiguration() {} 。。。。。。 }

通配規則：schema‐*.sql、data‐*.sql， 優先級第三高 eg：schema-emp.sql, schema-dept.sql； data-emp.sql ，data-dept.sql
默認規則：schema.sql，schema‐all.sql (或者關系，給用戶多個選擇)； 優先級第二高，
自定義規則：yml中配置，根據上面代碼，優先級高
spring:
datasource:
schema:
‐ classpath: department.sql
‐ classpath: user.sql
......
data:
‐ classpath: department_initData.sql
‐ classpath: user_initData.sql
......
自定義指定的SQL文件
經過測驗，schema.sql 和schema-all.sql 在resources目錄下並沒有生效，有待繼續查驗
6. jdbcTemplate操作數據庫
@Controller @RequestMapping("/user") public class UserController { @Autowired JdbcTemplate jdbcTemplate; @ResponseBody @RequestMapping("/getById2/{id}") public List<Map<String, Object>> selectByPrimaryKey2(@PathVariable Integer id){
//這種query is OK List<Map<String, Object>> maps = jdbcTemplate.queryForList("SELECT * FROM USER"); return maps; //以下幾種方式都會產生error,error信息見下文：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); } }
