我为我的网络应用程序预制了后端.在我的项目(SpringBoot + Maven)中,我想添加h2日期库.根据网站的教程:

1. 添加到application.properties

    server.port = 8088
    spring.h2.console.enabled=true
    spring.h2.console.path=/h2
    spring.datasource.url=jdbc:h2:mem:testdb
    spring.datasource.username=sa
    spring.datasource.password=
    spring.datasource.driverClassName=org.h2.Driver    //h2 seems to be NOT found
    spring.jpa.show-sql=true

2. 添加了对pom.xml的依赖项

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
    </dependency>

问题:

在application.properties中:"无法解析类或包'h2'"

全面检查: "检查Spring Boot应用程序.properties配置文件.突出显示未解析和弃用的配置键和无效值.仅适用于Spring Boot 1.2或更高版本."

当然,我的Spring Boot高于1.2(1.5.8).我在网上发现了类似的问题,但"重新编码依赖"不起作用,所以我仍然没有解决方案:).请帮忙.
