Java Spring引导jdbcAuthentication数据源未加载错误,java,spring,spring-boot,spring-security,Java,Spring,Spring Boot,Spring Security,我一直在为数据库身份验证应用程序开发SpringBoot。在本地主机上安装MySQL数据库。但问题是我甚至不能运行我的spring应用程序。我在Windows操作系统上使用Eclipse和maven。我创建的文件和错误如下： WebSecurityConfig.java： import org.springframework.context.annotation.Configuration; import org.springframework.beans.factory.annotation.

我一直在为数据库身份验证应用程序开发SpringBoot。在本地主机上安装MySQL数据库。但问题是我甚至不能运行我的spring应用程序。我在Windows操作系统上使用Eclipse和maven。我创建的文件和错误如下：

WebSecurityConfig.java：

import org.springframework.context.annotation.Configuration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import javax.sql.DataSource;
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired  
    private DataSource dxataSource;

    @Autowired
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.jdbcAuthentication().dataSource((DataSource) dxataSource).usersByUsernameQuery("select username,password, enabled from users where username=?");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin();
    }
}

Application.java：

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

@SpringBootApplication
public class Application {

     public static void main(String[] args) {

        SpringApplication.run(Application.class, args);
     }

}

HomeComtoller.java：

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

  @RestController
  public class HomeController {

   @GetMapping("/")
   public String index() {
       return "OK";
   }
 }

尝试运行应用程序（在Eclipse IDE上）时出现错误：

任何建议都会很有帮助。谢谢。

您的

pom.xml

文件中有一个错误。您在标记外添加了两个依赖项，并且忘记提到名为-“spring boot starter jdbc的依赖项版本。”

尝试用下面的pom文件替换它

可能不见了？您看到的spring.datasource.driver类名=com.mysql.jdbc.driverId是否丢失？spring.datasource.driver class name=com.mysql.jdbc.driverId你看，我更改了pom.xml文件，它工作了，非常感谢。我更改了pom.xml文件，它工作了，非常感谢。
