Question

我有以下代码。当我尝试执行它时，我得到了

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为“x”的bean时出错：表示不满意的依赖项通过字段'dataSource'：没有类型的限定bean 找到依赖项[javax.sql.DataSource]的[javax.sql.DataSource]：预计至少有1个豆有资格成为autowire候选人这种依赖。依赖注释： {@ org.springframework.beans.factory.annotation.Autowired（所需=真）}; 嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖项找到类型[javax.sql.DataSource]的限定bean [javax.sql.DataSource]：预计至少有1个符合条件的bean autowire候选人这种依赖。依赖注释： {@ org.springframework.beans.factory.annotation.Autowired（所需=真）}

我的切入点：

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);

    }
}

我尝试在resources

中添加application.properties个文件夹中的这些行

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/y
jdbc.username=a
jdbc.password=b

spring.datasource.url=jdbc:mysql://localhost:3306/y    spring.datasource.username=a
spring.datasource.password=b
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.driverClassName=com.mysql.jdbc.Driver

或者我尝试添加此上下文配置：

<!-- Initialization for data source -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/cfa"/>
    <property name="username" value="cfa_user"/>
    <property name="password" value="cfa_pw"/>
</bean>

这些都没有奏效。还有其他想法吗？谢谢！

我必须提到我的DAO正在扩展

public abstract class BaseDAO extends NamedParameterJdbcDaoSupport {
    private @Autowired DataSource dataSource;

    @PostConstruct
    public void initDataSource(){
        setDataSource(dataSource);
    }
}
