mybatis-guice mysql 未能加载 jdbc 驱动程序

mybatis-guice mysql failed to load jdbc driver

我正在尝试将 mybatis-guicemysql 一起使用,但我一直在捕获下一个异常:

查询数据库时出错。原因:java.sql.SQLException:在 UnpooledDataSource 上设置驱动程序时出错。原因:java.lang.ClassNotFoundException:com.mysql.jdbc.Driver

原因:java.sql.SQLException:在 UnpooledDataSource 上设置驱动程序时出错。原因:java.lang.ClassNotFoundException:org.hsqldb.jdbcDriver

这是我尝试使用的代码 运行:

public class DaoImpl implements Dao {
    @Inject
    private MyMapper mapper;

    public String getSomething() {
        return mapper.getSomething();
    }
}

public interface Dao {
    String getSomething();
}

public interface MyMapper {
    @Select("SELECT DATE_FORMAT(NOW(),'%d/%m/%Y %H:%i') as time")
    String getSomething();
}

Injector injector = Guice.createInjector(
        new MyBatisModule() {
            @Override
            protected void initialize() {
                install(JdbcHelper.MySQL);
                environmentId("development");

                bindDataSourceProviderType(PooledDataSourceProvider.class);
                bindTransactionFactoryType(JdbcTransactionFactory.class);
                addMapperClass(MyMapper.class);

                bindProperties(binder(), getMybatisProperties());
                bind(Dao.class).to(DaoImpl.class);
            }
        }
);

private Properties getMybatisProperties() {
    Properties myBatisProperties = new Properties();
    myBatisProperties.setProperty("JDBC.host", "127.0.0.1");
    myBatisProperties.setProperty("JDBC.port", "3306");
    myBatisProperties.setProperty("JDBC.schema", "my_schema");
    myBatisProperties.setProperty("JDBC.driver", "com.mysql.jdbc.Driver"));
    myBatisProperties.setProperty("JDBC.username", "root");
    myBatisProperties.setProperty("JDBC.password", "");
    myBatisProperties.setProperty("JDBC.autoCommit", "false");
    return myBatisProperties;
}

然后我尝试 运行: injector.getInstance(Dao.class).getSomething()

我试图删除 myBatisProperties.setProperty("JDBC.driver", "com.mysql.jdbc.Driver")); 但结果是一样的。

此外,经过几个小时的代码调试,install(JdbcHelper.MySQL);应该会自行添加驱动程序。这个假设正确吗?

mapper.getSomething();

抛出异常

想法???

您需要驱动程序 mysql-connector-java 或验证驱动程序的版本和您的 put mysql-connector-java-bin.jar 在库中
