Question

我一直致力于Spring boot for database authentication aplication。在localhost上安装MySQL数据库。但问题是我甚至无法运行我的弹簧应用程序。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";
   }
 }

我的pom.xml文件：

 </project>

我的application.properties文件：

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

尝试运行应用程序时出现错误（在Eclipse IDE上）：

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

任何建议和建议都会有所帮助。感谢。

您的pom.xml文件中存在错误。您已在标记之外添加了两个依赖项，并且忘记提及所谓的依赖项版本 - ＆＃34; spring-boot-starter -jdbc ＆＃34;

尝试将其替换为下面的pom文件。

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.springframework</groupId> <artifactId>gs-authenticating-ldap</artifactId> <version>0.1.0</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.6.RELEASE</version> </parent> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> <version>1.5.2.RELEASE</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.6</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.ldap</groupId> <artifactId>spring-ldap-core</artifactId> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-ldap</artifactId> </dependency> <dependency> <groupId>com.unboundid</groupId> <artifactId>unboundid-ldapsdk</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-test</artifactId> <scope>test</scope> </dependency> </dependencies>  <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
