在我的项目中，我正在使用JDBC，MySQL，Servlet，JSP。
为了测试我的DAO，我进行了一些单元测试，并且尝试使用JUnit和Unitils。
我收到此异常：

我的unitils-local.propreties：
database.userName=root
database.password=111111
database.storedIndentifierCase.mysql=mixed_case
dbUnit.datasetresolver.prefixWithPackageName=false
database.identifierQuoteString.mysql=none
database.schemaNames=TEST
database.dialect=mysql
database.driverClassName=com.mysql.jdbc.Driver
我的unitils.properties：
# Name or path of the user specific properties file. This file should contain the necessary parameters to connect to the
# developer's own unit test schema. It is recommended to override the name of this file in the project specific properties
# file, to include the name of the project. The system will try to find this file in the classpath, the user home folder
# (recommended) or the local filesystem.
unitils.configuration.localFileName=unitils-local.properties

dbUnit.datasetresolver.prefixWithPackageName=false
我的数据集选项：
<?xml version="1.0" encoding="UTF-8"?>
<dataset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<CLIENT ID="1" CLIENT_NAME="clientName" CLIENT_LAST_NAME="clientLastName"
EMAIL="email" ADDRESS="address" PASSWORD="password"
PHONE="phone" SECOND_PHONE="secondPhone" THIRD_PHONE="thirdPhone" CREATE_DATE="2015-10-05 08:35:25"/>
<CLIENT_GRANT ID="1" ID_CLIENT="1" ADMIN="0" MODERATOR="0" ACTIVE="1"/>
</dataset>
还有我要测试的部分测试类：
@Transactional(TransactionMode.ROLLBACK)
@DataSet("ClientDaoImplTest.xml")
public class ClientDaoImplTest extends UnitilsJUnit4 {
@TestDataSource
DataSource dataSource;
ClientDaoImpl clientDao = null;
ClientGrantDaoImpl clientGrantDao = null;
@Before
public void init() {
clientDao = new ClientDaoImpl(dataSource);
clientGrantDao = new ClientGrantDaoImpl(dataSource);
TransactionHandlerImpl.setDataSource(dataSource);
clientDao.setCurrentLocalConnection(ConnectionHolder.getLocalConnection());
clientGrantDao.setCurrentLocalConnection(ConnectionHolder.getLocalConnection());
}
@After
public void destroy() {
clientDao = null;
clientGrantDao = null;
}
@Test
public void testAddNew() {
final User user = new User();
user.setEmail("email");
user.setAddress("address");
user.setPassword("password");
user.setClientName("clientName");
user.setClientLastName("clientLastName");
user.setPhone("phone");
final ClientGrant clientGrant = user.getClientGrant();
clientGrant.setClientId(user.getId());
clientGrant.setActive(true);
user.setClientGrant(clientGrant);
executeTest(new Transaction<Long>() {
@Override
public void doTransaction() throws Exception {
Long clientId = clientDao.addNew(user);
user.setId(clientId);
clientGrantDao.addNew(user.getClientGrant());
assertTrue(assertClient(clientDao.get(clientId), user));
}
});
}
我知道我的数据库选项有问题。
您能帮我找到解决此问题的方法吗？
谢谢。
更新：更改我的unitils-local.properties中的参数后：
从：
database.identifierQuoteString.mysql=none
至：
database.identifierQuoteString.mysql=auto

也许对这个问题有一些新的变种或想法？谢谢。
最佳答案
我会说问题出在这里：
database.identifierQuoteString.mysql=none
尝试将其设置为以下内容：
database.identifierQuoteString.mysql=auto
最终，类MySqlDbSupport中有一个bug。如果在属性文件中将
database.identifierQuoteString.mysql属性设置为none，则类DbSupport中名为identifierQuoteString的私有字段将设置为null。 MySqlDbSupport中的toCorrectCaseIdentifier方法获取此字段的值，但是在将其传递给String.startsWith之前忘记进行空检查。因此，我们得到一个NullPointerException。使用
auto询问数据库要使用的标识符-引号字符串。我不明白您为什么要使用除此以外的任何其他内容。关于java - Unitils数据库异常，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/33477014/
