Spring启动jdbctemplate无法加载驱动类

时间:2017-03-14 08:36:05

标签: spring spring-boot spring-jdbc

我正在尝试在我的 Spring boot-angularjs 应用程序中使用JdbcTemplate

这是我的 application.properties 文件,位于 src / main / resources / 中:

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/BlurAdmin
spring.datasource.username=root
spring.datasource.password=password

这是我的 UsersRepository.java

@Repository
public class UsersRepository implements UserDao{

  private JdbcTemplate template;

  @Autowired
  public UsersRepository(JdbcTemplate template){
      this.template = template;
  }


  @Override
  public boolean save(final User user){
      String query = "insert into BlurAdminUsers (username,email,password,role) values (?,?,?,?)";

      return template.execute(query, new PreparedStatementCallback<Boolean>(){
          @Override
          public Boolean doInPreparedStatement(PreparedStatement ps) throws SQLException, DataAccessException {

              ps.setString(1, user.getUsername());
              ps.setString(2, user.getEmail());
              ps.setString(3,user.getPassword());
              ps.setString(4, user.getRole());

              return ps.execute();
          }

      });

  }

运行应用程序时出现以下错误:

答案 0 :(得分:4)

缺少依赖性。 对于Maven,将其添加到您的POM.xml:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.5</version>
</dependency>

或Gradle的这个:

compile group: 'mysql', name: 'mysql-connector-java', version: '6.0.5'
