下面是我的主要课程

package com.example;



import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
@EnableAutoConfiguration
public class SpringDemoApplication {


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


    }


}

以前，我在 Eclipse 上运行简单的 Spring Boot 应用程序时也遇到了问题。但是，在 IntelliJ 上运行良好。然后我在 Eclipse 上安装了 Spring Suite，之后嵌入式 tomcat 开始工作。但是现在，数据库配置有问题。请协助。我哪里错了？

请在此处查看Structure。

【问题讨论】：

重复stackoverflow.com/questions/24074749/…
您是否尝试过清理项目？嵌入式数据库使用默认配置，除非被覆盖
如果你更新你的 S,B 父版本也不会有什么坏处 1.4.1.RELEASE
@Georgesvanhoutte，SB 版本已更新。还是一样的错误。
@Saravana，上面的堆栈跟踪没有任何配置。

标签： java maven spring-boot jar h2

【解决方案1】：

你有没有类似的东西，

spring.datasource.url=jdbc:h2:mem:persondb
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

在您的 application.properties 文件中？

【讨论】：

嵌入式数据库使用默认的自动配置，没有这个配置也可以工作
在属性文件中添加这些会给我以下错误
引起：java.lang.IllegalStateException：无法加载驱动类：org.h2.Driver

【解决方案2】：

在您的 application.properties 中尝试以下 H2 配置。尽管 Spring boot 提供了合理的默认值，但您可以尝试调整以下这些配置，并且可能很容易切换到其他数据库以适应更高的环境。

### Enable H2 Console Access 
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console

### Define H2 Datasource configurations
spring.datasource.platform=h2
spring.datasource.url=jdbc:h2:mem:yourDB
spring.datasource.username=yourUser
spring.datasource.password=yourPwd
spring.datasource.driver-class-name=org.h2.Driver

【讨论】：

【解决方案3】：

我遇到了同样的问题，我发现它是由损坏的 H2 依赖项的 JAR 文件引起的。 Refer to this link about corrupted jars

你要做的是删除你的 .m2 maven 本地存储库中的 h2 相关 jar 文件。例如我删除了以下目录；

C:\Users\<user>\.m2\repository\com\h2database\

详细说明

A - 清理项目

我做了一个maven clean，所有的build binaries都删除了，输出如下，没什么特别的；

D:\SpringSTS\sts-tezgah\conquisitio>mvn clean
[INFO] Scanning for projects...
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] Building conquisitio 0.0.1-SNAPSHOT

[INFO] Final Memory: 8M/155M
[INFO] ------------------------------------------------------------------------

B - 运行 mvn install 并检查可能的错误

这里是 mvn install 命令的输出（我将其减半）。您可以看到有“invalid LOC header (bad signature)”警告，这意味着相关的.jar文件已损坏；

D:\SpringSTS\sts-tezgah\conquisitio>mvn install
[INFO] Scanning for projects...
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] Building conquisitio 0.0.1-SNAPSHOT

[INFO] Compiling 1 source file to D:\SpringSTS\sts-tezgah\conquisitio\target\test-classes

[INFO] --- maven-surefire-plugin:2.18.1:test (default-test) @ conquisitio ---
[INFO] Surefire report directory: D:\SpringSTS\sts-tezgah\conquisitio\target\surefire-reports

所以，重要的警告如下；

[WARNING] error reading C:\Users\Levent\.m2\repository\com\h2database\h2\1.4.190\h2-1.4.190.jar; invalid LOC header (bad signature)

[WARNING] error reading C:\Users\Levent\.m2\repository\com\h2database\h2\1.4.190\h2-1.4.190.jar; invalid LOC header (bad signature)

两者都暗示 h2database jars，因为这些 jars 已损坏，spring boot 无法加载相关类。

C - 解决方案

只需删除 mvn install 命令输出中出现的 maven 缓存中的相关依赖项。

删除下的所有内容；

C:\Users\Levent\.m2\repository\com\h2database\

D - 结果

Maven automatically downloads the related jar files and project is running ok with the new uncorrupted jar files;

D:\SpringSTS\sts-tezgah\conquisitio>mvn clean install

【讨论】：

【解决方案4】：

如果上述解决方案不适用于您的情况在 application.properties 中尝试以下操作

                  spring.h2.console.enabled=true
                  spring.datasource.platform=h2
                  spring.jpa.show-sql=true

【讨论】：

【解决方案5】：

您必须在 pom.xml 中显式添加 h2 依赖项：

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <scope>runtime</scope>
</dependency>

或build.gradle:

runtimeOnly "com.h2database:h2"

你需要定义方言/平台：

spring:
  datasource:
    url: jdbc:h2:mem:testdb
    driverClassName: org.h2.Driver
    username: sa
    password: password
  jpa:
    database.platform: org.hibernate.dialect.H2Dialect
    show-sql: true

或在application.properties中以相应的形式作为属性

【讨论】：

【解决方案6】：

请确保application.properties 文件中的每个配置行中没有尾部空格。

如果org.h2.Driver 右侧有如下空格，请删除它们，它会正常运行。

spring.datasource.driverClassName=org.h2.Driver

我在将教程网站的内容复制到我的 Spring boot applicaiton.properties 时发现了类似的问题。
