示例1: testRemoteConnectionProperties

import java.sql.Connection; //导入方法依赖的package包/类
@Test public void testRemoteConnectionProperties() throws Exception {
  ConnectionSpec.getDatabaseLock().lock();
  try (AvaticaConnection conn = (AvaticaConnection) DriverManager.getConnection(url)) {
    String id = conn.id;
    final Map<String, ConnectionPropertiesImpl> m = ((RemoteMeta) getMeta(conn)).propsMap;
    assertFalse("remote connection map should start ignorant", m.containsKey(id));
    // force creating a connection object on the remote side.
    try (final Statement stmt = conn.createStatement()) {
      assertTrue("creating a statement starts a local object.", m.containsKey(id));
      assertTrue(stmt.execute("select count(1) from EMP"));
    }
    Connection remoteConn = getConnection(FullyRemoteJdbcMetaFactory.getInstance(), id);
    final boolean defaultRO = remoteConn.isReadOnly();
    final boolean defaultAutoCommit = remoteConn.getAutoCommit();
    final String defaultCatalog = remoteConn.getCatalog();
    final String defaultSchema = remoteConn.getSchema();
    conn.setReadOnly(!defaultRO);
    assertTrue("local changes dirty local state", m.get(id).isDirty());
