java - 最新版本的 spring boot 问题

Question

在我的带有 MySql 数据库的 spring boot 应用程序中。在服务器启动时出现非常意外的异常 - 主类。

我正在尝试通过“Run As Java Application”和“Boot Dashboard”在 Eclipse 中使用 STS 运行

在版本 1.5.3 上:

Description:

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
    - Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
    - Bean method 'dataSource' not loaded because @ConditionalOnBean (types: org.springframework.boot.jta.XADataSourceWrapper; SearchStrategy: all) did not find any beans


Action:

Consider revisiting the conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.

是 SpringBoot 的问题还是我遗漏了什么？

之前用spring boot 1.4.0成功

在您的实体类中，您没有主键表，如果不为该表创建主键，则无法通过引导访问该表。必须将任何一列声明为主键。即使我也遇到了不依赖性异常，然后我发现了我的错误。所以像这样尝试，

@Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "org.hibernate.id.UUIDGenerator")
    @Column(name = "DN_ID", nullable = false, unique = true)    
    private String enquiryId;
