springboot利用ConfigurationProperties注解配置数据源无法读取配置信息

@Bean(name = "pq")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSourcePq() {
        return DataSourceBuilder.create().build();     
    }

#配置信息
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    #MySQL配置
    driverClassName: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/graduate?useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: root
    password: root

@Bean(name = "pq")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSourcePq() {
        //return DataSourceBuilder.create().build();
        return new DruidDataSource();
    }
