[英]Spring boot @Autowired repository instance null when using spring security
[英]Spring @Autowired instance is null
我目前正在嘗試設置REST Service Spring應用程序,並實現了一個模型及其控制器+ dao和服務以與MySQL數據庫進行通信。
現在,我的AccountController是帶有注釋的@RestController的bean,而AccountService是@Component Bean。 AccountService擁有一個@ Autowire'd AccountDao成員,而AccountController擁有一個@ Autowire'd AccountService成員。
dataAccess.xml如下:
<?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.xsd">
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/fashion" />
<property name="username" value="root" />
<property name="password" value="fashion" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingResources">
<list>
<value>de/appsiting/fashion/model/Account.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQL5Dialect
</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<bean id="jdbcExceptionTranslator" class="org.springframework.jdbc.support.SQLErrorCodeSQLExceptionTranslator">
<property name="dataSource">
<ref bean="dataSource" />
</property>
</bean>
<bean id="accountDao" class="de.appsiting.fashion.persistence.AccountDao" />
</beans>
但是, Account.hbm.xml
被塗成紅色,表明應用程序找不到它。 因此,我的第一個問題是,為什么不從resources文件夾中根目錄找到.hbm.xml?
如下所示填充serviceBeans.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" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

<bean id="hibernateStringEncryptor" class="org.jasypt.hibernate4.encryptor.HibernatePBEStringEncryptor">

</property>
<property name="algorithm">

</property>
<property name="password">
<value>jasypt</value>
</property>
</bean>
<bean id="accountService" class="de.appsiting.fashion.service.AccountService">
<property name="accountDao" ref="accountDao" />
</bean>
<!-- *** TX LAYER -->
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:advice id="tx.advice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED" read-only="false" />
<tx:method name="get*" propagation="REQUIRED" read-only="false" />
</tx:attributes>
</tx:advice>
<!-- *** AOP -->
<aop:config>
<aop:pointcut id="accountServiceMethods" expression="execution(* de.appsiting.fashion.service.AccountService.*(..))" />
<aop:advisor advice-ref="tx.advice" pointcut-ref="accountServiceMethods" />
</aop:config>
</beans>
現在,當運行我的AccountTest時 ,accountService為null,因此測試失敗:
import de.appsiting.fashion.service.AccountService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.junit.Test;
/**
* Created by mak on 4/22/16.
*/
public class AccountTest {
private static Logger log = Logger.getLogger(AccountTest.class);
@Autowired
private AccountService accountService;
@Test
public void testCreateAccount() throws Exception {
Account account = new Account();
account.setUsername("testfashion");
account.setPassword("testfashion");
account.setEmail("test@appsiting");
accountService.addAccount(account);
}
}
為什么會這樣?
您應該使用SpringJUnit4ClassRunner來初始化應用程序上下文,以便依賴項注入能夠運行。
您在測試中缺少兩種配置。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"Location of xml files that you need to load for tests to run"})
public class AccountTest {
}
以上配置將為您的測試加載上下文。 或者,您可以在設置方法中加載測試的應用程序上下文,然后使用該上下文獲取帳戶服務。
我認為您應該在serviceBeans.xml中添加以下內容,
<bean id="accountDao" class="de.appsiting.fashion.persistence.AccountDao" />
並刪除AccountService類中的@Autowired AccountDao批注,並添加一個AccountDao的設置器。
