+### 67.1. 配置一个数据源
+
+想要覆盖默认的设置只需要定义一个你自己的DataSource类型的`@Bean`。Spring Boot提供一个工具构建类DataSourceBuilder，可用来创建一个标准的DataSource（如果它处于classpath下），或者仅创建你自己的DataSource，然后将它和在[Section 23.7.1, “Third-party configuration”](http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-external-config-3rd-party-configuration)解释的一系列Environment属性绑定。
+
+比如：
+```java
+@Bean
+@ConfigurationProperties(prefix="datasource.mine")
+public DataSource dataSource() {
+    return new FancyDataSource();
+}
+```
+```java
+datasource.mine.jdbcUrl=jdbc:h2:mem:mydb
+datasource.mine.user=sa
+datasource.mine.poolSize=30
+```
+具体参考'Spring Boot特性'章节中的[Section 28.1, “Configure a DataSource”](http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-configure-datasource)和[DataSourceAutoConfiguration](http://github.com/spring-projects/spring-boot/tree/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration.java)类源码。
