Java jdbc更新查询不使用derby数据库和SpringJUnit4ClassRunner进行单元测试

我在尝试进行单元测试时遇到问题

测试类很简单，如：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/job-runner-context.xml})
public class AtualizarDataServiceTest {

    @Autowired
    DataSource testDataSource;

    @Autowired
    Service service;

    @Before
    public void setUp() throws DatabaseUnitException, SQLException{
        service.setDataSource(testDataSource);
    }

    @Test
    public final void testUpdateDate() throws SQLException {
        assertTrue(verifyDate());
        service.updateDate();
        assertFalse(verifyDate()); //Assert brokes here
    }

    private boolean verifyDate(){
        SimpleJdbcTemplate consultaTemplate = new SimpleJdbcTemplate(testDataSource);
        int count = consultaTemplate.queryForInt("SELECT COUNT(*) FROM MY_TABLE");
        return count == 0;
    }
}

public class Service {

    private DataSource dataSource;

    public void updateDate(){
        SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(getDataSource());
        String query = "UPDATE MY_TABLE SET DT_UPDATE_OPERATION = ?";
        jdbcTemplate.update(query, new Object[]{new java.sql.Date(Calendar.getInstance().getTime().getTime())});
    }

    public DataSource getDataSource() {
        return dataSource;
    }

    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

}

<context:annotation-config/>
    <context:component-scan base-package="my.package"/>

    <bean class="my.package.Service"/>

    <bean id="testDataSource" class="com.read.only.MyBasicDataSource" destroy-method="close" lazy-init="true">
        <property name="jdbcReference" value="derby" />
    </bean> 

<com:jdbcReference name="derby" type="DATABASE">
        <com:credential user="" password="" />
        <com:autocommit arg="false" />
        <com:databaseConfig driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
            url="jdbc:derby:dbderby;create=true" databaseName="ANY" />
    </com:jdbcReference> 

服务：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/job-runner-context.xml})
public class AtualizarDataServiceTest {

    @Autowired
    DataSource testDataSource;

    @Autowired
    Service service;

    @Before
    public void setUp() throws DatabaseUnitException, SQLException{
        service.setDataSource(testDataSource);
    }

    @Test
    public final void testUpdateDate() throws SQLException {
        assertTrue(verifyDate());
        service.updateDate();
        assertFalse(verifyDate()); //Assert brokes here
    }

    private boolean verifyDate(){
        SimpleJdbcTemplate consultaTemplate = new SimpleJdbcTemplate(testDataSource);
        int count = consultaTemplate.queryForInt("SELECT COUNT(*) FROM MY_TABLE");
        return count == 0;
    }
}

public class Service {

    private DataSource dataSource;

    public void updateDate(){
        SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(getDataSource());
        String query = "UPDATE MY_TABLE SET DT_UPDATE_OPERATION = ?";
        jdbcTemplate.update(query, new Object[]{new java.sql.Date(Calendar.getInstance().getTime().getTime())});
    }

    public DataSource getDataSource() {
        return dataSource;
    }

    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

}

<context:annotation-config/>
    <context:component-scan base-package="my.package"/>

    <bean class="my.package.Service"/>

    <bean id="testDataSource" class="com.read.only.MyBasicDataSource" destroy-method="close" lazy-init="true">
        <property name="jdbcReference" value="derby" />
    </bean> 

<com:jdbcReference name="derby" type="DATABASE">
        <com:credential user="" password="" />
        <com:autocommit arg="false" />
        <com:databaseConfig driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
            url="jdbc:derby:dbderby;create=true" databaseName="ANY" />
    </com:jdbcReference> 

job runner context.xml

重要部分：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/job-runner-context.xml})
public class AtualizarDataServiceTest {

    @Autowired
    DataSource testDataSource;

    @Autowired
    Service service;

    @Before
    public void setUp() throws DatabaseUnitException, SQLException{
        service.setDataSource(testDataSource);
    }

    @Test
    public final void testUpdateDate() throws SQLException {
        assertTrue(verifyDate());
        service.updateDate();
        assertFalse(verifyDate()); //Assert brokes here
    }

    private boolean verifyDate(){
        SimpleJdbcTemplate consultaTemplate = new SimpleJdbcTemplate(testDataSource);
        int count = consultaTemplate.queryForInt("SELECT COUNT(*) FROM MY_TABLE");
        return count == 0;
    }
}

public class Service {

    private DataSource dataSource;

    public void updateDate(){
        SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(getDataSource());
        String query = "UPDATE MY_TABLE SET DT_UPDATE_OPERATION = ?";
        jdbcTemplate.update(query, new Object[]{new java.sql.Date(Calendar.getInstance().getTime().getTime())});
    }

    public DataSource getDataSource() {
        return dataSource;
    }

    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

}

<context:annotation-config/>
    <context:component-scan base-package="my.package"/>

    <bean class="my.package.Service"/>

    <bean id="testDataSource" class="com.read.only.MyBasicDataSource" destroy-method="close" lazy-init="true">
        <property name="jdbcReference" value="derby" />
    </bean> 

<com:jdbcReference name="derby" type="DATABASE">
        <com:credential user="" password="" />
        <com:autocommit arg="false" />
        <com:databaseConfig driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
            url="jdbc:derby:dbderby;create=true" databaseName="ANY" />
    </com:jdbcReference> 

jdbc连接属性：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/job-runner-context.xml})
public class AtualizarDataServiceTest {

    @Autowired
    DataSource testDataSource;

    @Autowired
    Service service;

    @Before
    public void setUp() throws DatabaseUnitException, SQLException{
        service.setDataSource(testDataSource);
    }

    @Test
    public final void testUpdateDate() throws SQLException {
        assertTrue(verifyDate());
        service.updateDate();
        assertFalse(verifyDate()); //Assert brokes here
    }

    private boolean verifyDate(){
        SimpleJdbcTemplate consultaTemplate = new SimpleJdbcTemplate(testDataSource);
        int count = consultaTemplate.queryForInt("SELECT COUNT(*) FROM MY_TABLE");
        return count == 0;
    }
}

public class Service {

    private DataSource dataSource;

    public void updateDate(){
        SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(getDataSource());
        String query = "UPDATE MY_TABLE SET DT_UPDATE_OPERATION = ?";
        jdbcTemplate.update(query, new Object[]{new java.sql.Date(Calendar.getInstance().getTime().getTime())});
    }

    public DataSource getDataSource() {
        return dataSource;
    }

    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

}

<context:annotation-config/>
    <context:component-scan base-package="my.package"/>

    <bean class="my.package.Service"/>

    <bean id="testDataSource" class="com.read.only.MyBasicDataSource" destroy-method="close" lazy-init="true">
        <property name="jdbcReference" value="derby" />
    </bean> 

<com:jdbcReference name="derby" type="DATABASE">
        <com:credential user="" password="" />
        <com:autocommit arg="false" />
        <com:databaseConfig driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
            url="jdbc:derby:dbderby;create=true" databaseName="ANY" />
    </com:jdbcReference> 

起初我认为问题与提交问题有关，但我尝试将自动提交属性的值设置为“true”，并手动调用

testDataSource.getConnection（）.commit（）

，但没有成功。代码和方法工作正常，但测试没有更新derby数据库。在其他测试类中，数据在同一数据库中预设为

dbUnit

，代码正常工作。这个答案给出了我检查过的可能问题的一般列表，并且我正在以相同的模式对相同的表进行读写。我遗漏了什么吗？

尝试设置

对于我发布的问题，我验证了自动提交，如果我正在写入正确的数据库，但没有检查明显的：您不能更新没有寄存器的表查询

更新我的表集DT\u UPDATE\u操作=？

应用于空表，计数查询将始终返回0。我刚刚配置了测试，使DbUnit从xml文件向数据库导入状态。抱歉给你添麻烦了
