org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined


Error creating bean with name defined in file


context-idgen.xml


관련 오류로 서비스를 실행할 수 없다고 메시지가 뜰때, 몇시간을 찾아 헤대다가. 결국 허무한.


톰캣7 시동시 스프링프레임워크에서 위와 같은 오류가 날때,  찾기도 많이 찾고 찾았지만, 근본적인 원인이 따로 있었다. 본래 소스 및 설정 파일 반영을  젠킨스를 통해서 하고 있었는데, 파일이 깨졌다는 사실을 아무도 알지 못했다.  이런 쓰~~~




Spring: “NoSuchBeanDefinitionException: No bean named 'dataSource' is defined” when testing


I have been trying to test the DAO layer of an application, however I keep getting this error.

Here is the Test class

RegionDAOTest.java

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.teamw.ibt.dao.impl.RegionDAOImpl;
import com.teamw.ibt.model.Region;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(locations = "classpath:app-context.xml")
public class RegionDAOTest extends AbstractDAOTest {

 @Autowired
 private JdbcTemplate jdbcTemplate;
 @Autowired
 private RegionDAOImpl regionDAOImpl;

 @Before
 public void setUp(){
 }

 @After
 public void tearDown(){
 }

 @Test
    public void testContext() {
        assertNotNull(regionDAOImpl);
    }

 @Test
 public void FindByCodeTest() {
    Region region = regionDAOImpl.findByCode("1");
    assertEquals('1', region.getCode());
    assertEquals("Region 1", region.getName());
 }
}

RegionDAOImpl.java

@Repository
public class RegionDAOImpl implements RegionDAO {

@Autowired
private JdbcTemplate jdbcTemplate;

public RegionDAOImpl() {
}

public RegionDAOImpl(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}


public void insert(Region region) {
    String query = "INSERT INTO IBT.REGION (code, name) VALUES ('" + region.getCode() + "','" + region.getName() + "');";
    jdbcTemplate.update(query);
}

public Region findByCode(String code) {
    String query = "SELECT * FROM IBT.REGION WHERE CODE = '" + code + "';";
    return jdbcTemplate.query(query, new ResultSetExtractor<Region>() {
        @Override
        public Region extractData(ResultSet rs) throws SQLException, DataAccessException {
            if (rs.next()) {
                return new Region(
                    rs.getString("code"),
                    rs.getString("name")
                );
            }

            return null;
        }
    });
}
}

app-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ">

<!-- Initialization for data source -->
 <bean id="dataSource" 
   class="org.springframework.jdbc.datasource.DriverManagerDataSource">
   <property name="driverClassName" value="org.h2.Driver"/>
   <property name="url" value="jdbc:h2:mem"/>
   <property name="username" value="SA"/>
   <property name="password" value="test"/>
 </bean>

 <bean id="JdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource"></property>
 </bean>

<bean id="regionDAOImpl" name="regionDAOImpl" class="com.teamw.ibt.dao.impl.RegionDAOImpl">
  <constructor-arg ref="jdbcTemplate"/>
</bean>
</beans>

As far as I know, I have set up everything correctly, but for some reason it says dataSource is not defined.

EDIT: Here is the log

You have multiple wiring of JdbcTemplate in RegionDao, which you will need to change.

In the app-context, you are only referencing dataSource as a constructor-arg. If that is what you wish to do, then app-context stays as-is, and you will need to get rid of the below method -

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}

OR , you could get rid of the constructor with JdbcTemplate and then wire the dataSource as a 'property' in the app-context.

<bean id="regionDAOImpl" name="regionDAOImpl" class="com.teamw.ibt.dao.impl.RegionDAOImpl">
    <!-- constructor-arg ref="jdbcTemplate" -->
    <property name="jdbcTemplate" ref="jdbcTemplate"></property>
</bean>
