spring boot整合使用jdbcTemplate

1)pom文件引入

<parent>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-parent</artifactId>

            <version>1.5.2.RELEASE</version>

      </parent>

      <dependencies>

            <dependency>

                  <groupId>org.springframework.boot</groupId>

                  <artifactId>spring-boot-starter-jdbc</artifactId>

            </dependency>

            <dependency>

                  <groupId>mysql</groupId>

                  <artifactId>mysql-connector-java</artifactId>

                  <version>5.1.21</version>

            </dependency>

            <dependency>

                  <groupId>org.springframework.boot</groupId>

                  <artifactId>spring-boot-starter-test</artifactId>

                  <scope>test</scope>

            </dependency>

            <dependency>

                  <groupId>org.springframework.boot</groupId>

                  <artifactId>spring-boot-starter-web</artifactId>

            </dependency>

      </dependencies>

2)application.properties新增配置

spring.datasource.url=jdbc:mysql://localhost:3306/test

spring.datasource.username=root

spring.datasource.password=root

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3)创建一个接口,并创建一个方法

4)继承接口,实现方法

5)访问路径

6)启动类

注意

@AutoWired
byType方式。把配置好的Bean拿来用,完成属性、方法的组装,它可以对类成员变量、方法及构
造函数进行标注,完成自动装配的工作。
当加上(required=false)时,就算找不到bean也不报错
