    <p>I'm having problems with Spring transactions. I really need help as I can't figure out why personsDao2 is not rolled back as should (see assert below commented with "FAILS!"). Any input?</p> <p>My Eclipse project is available for download at <a href="http://www52.zippyshare.com/v/4142091/file.html" rel="nofollow">http://www52.zippyshare.com/v/4142091/file.html</a>. All dependencies are there so it's easy to get going.</p> <pre><code>import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; import com.google.common.collect.Lists; public class MyInnerClass { private PersonsDao personsDao; public MyInnerClass() { } public PersonsDao getPersonsDao() { return personsDao; } public void setPersonsDao(PersonsDao personsDao) { this.personsDao = personsDao; } @Transactional(propagation = Propagation.REQUIRES_NEW, noRollbackFor = Exception.class) public void method() { personsDao.createPersons(Lists.newArrayList(new Person("Eva"))); } } import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; import com.google.common.collect.Lists; public class MyOuterClass { private MyInnerClass myInnerClass; private PersonsDao personsDao; public MyInnerClass getMyInnerClass() { return myInnerClass; } public void setMyInnerClass(MyInnerClass myInnerClass) { this.myInnerClass = myInnerClass; } public void setMyInnerClass() { } public PersonsDao getPersonsDao() { return personsDao; } public void setPersonsDao(PersonsDao personsDao) { this.personsDao = personsDao; } public MyOuterClass() { } @Transactional(propagation = Propagation.REQUIRED, rollbackFor=Exception.class) public void method() { try { personsDao.createPersons(Lists.newArrayList(new Person("Adam"))); throw new RuntimeException("Forced rollback"); } finally { myInnerClass.method(); } } } public class Person { public Person(String name) { this.name = name; } public String getName() { return name; } @Override public String toString() { return "Customer [name=" + name + "]"; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Person other = (Person) obj; if (name == null) { if (other.name != null) return false; } else if (!name.equals(other.name)) return false; return true; } private String name; } import java.sql.ResultSet; import java.sql.SQLException; import java.util.HashMap; import java.util.List; import java.util.Map; import javax.sql.DataSource; import org.springframework.jdbc.core.RowMapper; import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate; import org.springframework.jdbc.core.namedparam.SqlParameterSource; import org.springframework.jdbc.core.namedparam.SqlParameterSourceUtils; public class PersonsDao { public PersonsDao(DataSource dataSource, String tableName) { namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource); this.tableName = tableName; } public List&lt;Person&gt; getPersons() { Map&lt;String, Object&gt; namedParameters = new HashMap&lt;String, Object&gt;(); String getCustomers = "SELECT name FROM " + tableName + " ORDER BY name ASC"; return namedParameterJdbcTemplate.query(getCustomers, namedParameters, getRowMapper()); } public void createPersons(List&lt;Person&gt; customers) { SqlParameterSource[] params = SqlParameterSourceUtils.createBatch(customers.toArray()); String createCustomer = "INSERT INTO " + tableName + " VALUES(:name)"; namedParameterJdbcTemplate.batchUpdate(createCustomer, params); } public void deleteCustomers() { Map&lt;String, Object&gt; namedParameters = new HashMap&lt;String, Object&gt;(); String deleteCustomers = "DELETE FROM " + tableName; namedParameterJdbcTemplate.update(deleteCustomers, namedParameters); } private static RowMapper&lt;Person&gt; getRowMapper() { return new RowMapper&lt;Person&gt;() { @Override public Person mapRow(ResultSet arg0, int arg1) throws SQLException { return new Person(arg0.getString("name")); } }; } private NamedParameterJdbcTemplate namedParameterJdbcTemplate; private String tableName; } import static org.junit.Assert.*; import javax.annotation.Resource; import org.junit.After; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.transaction.annotation.Transactional; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "/beans.xml") @Transactional(rollbackFor = Exception.class) public class PersonsDaoTest { @Resource private MyInnerClass myInnerClass; @Resource private MyOuterClass myOuterClass; @Test(expected = Exception.class) public void test() { myOuterClass.method(); fail(); } @After public void after() { assertEquals(1, myInnerClass.getPersonsDao().getPersons().size()); assertEquals(0, myOuterClass.getPersonsDao().getPersons().size()); } @Before public void before() { myInnerClass.getPersonsDao().deleteCustomers(); myOuterClass.getPersonsDao().deleteCustomers(); assertEquals(0, myInnerClass.getPersonsDao().getPersons().size()); assertEquals(0, myOuterClass.getPersonsDao().getPersons().size()); } } </code></pre>

    1. COIt'd be much better if you described the issue here and included code.

    2. COThey appear to be pointed at the same database, it is confusing why you think 2 won't see the change made by 1?

    3. COThey point to the same db but to different tables---persons1 and persons2. The persons1 table is used by the inner class and persons2 table is used by the outer class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
