Spring Boot jdbcAuthentication dataSource未加載錯誤

Question

我一直在從事用於數據庫身份驗證應用程序的Spring Boot。 在本地主機上安裝MySQL數據庫。 但是問題是我什至無法運行我的spring應用程序。 我在Windows OS上將Eclipse與maven一起使用。 我創建的文件和錯誤如下：

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";
   }
 }

我的pom.xml文件：

     </build>
 </project>

我的application.properties文件：

spring.datasource.url=jdbc:mysql://localhost:3306/testdb
spring.datasource.username=test
spring.datasource.password=password

當我嘗試運行應用程序時（在Eclipse IDE上）出現錯誤：

Field dxataSource in auth.ldap.WebSecurityConfig required a bean of type 'javax.sql.DataSource' that could not be found.
- Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'
- Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required classes 'javax.transaction.TransactionManager', 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType

任何建議都將真正有幫助。 謝謝。

Answer 1

pom.xml文件中有一個錯誤。您已經在標記之外添加了兩個依賴項，並且還忘了提及名為“ spring-boot-starter-jdbc ”的依賴項的版本。

嘗試用下面的pom文件替換它。
