我正在尝试使用嵌入式 h2 设置一个非常简单的 ormlite 堆栈。该应用程序由于NoSuchMethodError
in ormlite 而崩溃:
Caused by: java.lang.NoSuchMethodError: com.j256.ormlite.db.DatabaseType.setDriver(Ljava/sql/Driver;)V
at com.j256.ormlite.jdbc.JdbcConnectionSource.initialize(JdbcConnectionSource.java:133)
at com.j256.ormlite.jdbc.JdbcConnectionSource.<init>(JdbcConnectionSource.java:112)
at com.j256.ormlite.jdbc.JdbcConnectionSource.<init>(JdbcConnectionSource.java:70)
at com.heyworld.resteasy.repositories.LocomotivesRepository.<init>(LocomotivesRepository.java:20)
提出 ormlite 的来源说databaseType.loadDriver();
有一个未经处理的ClassNotFound
异常并且databaseType.setDriver(DriverManager.getDriver(url));
(它实际抱怨的行)无法解决方法setDriver()
。
我在这里有什么明显的遗漏吗?也许缺少类路径依赖项?
这是我的存储库:
package heyworld.resteasy.repositories;
import com.j256.ormlite.dao.Dao;
import com.j256.ormlite.dao.DaoManager;
import com.j256.ormlite.db.H2DatabaseType;
import com.j256.ormlite.jdbc.JdbcConnectionSource;
import com.j256.ormlite.support.ConnectionSource;
import heyworld.resteasy.model.Locomotive;
import java.sql.SQLException;
import java.util.List;
public class LocomotivesRepository {
private Dao<Locomotive, Integer> locomotiveDao;
String databaseUrl = "jdbc:h2:mem:locomotives";
public LocomotivesRepository() {
ConnectionSource connectionSource = null;
try {
connectionSource = new JdbcConnectionSource(databaseUrl, new H2DatabaseType());
locomotiveDao = DaoManager.createDao(connectionSource, Locomotive.class);
} catch (SQLException e) {
e.printStackTrace();
}
}
public List<Locomotive> list() {
try {
return locomotiveDao.queryForAll();
} catch (SQLException e) {
e.printStackTrace();
return list();
}
}
}
