XML文件應該是對的，因爲我寫了一個簡單的MVC測試演示，它的工作原理well.But如果我寫這樣的，自動裝配Autowired依賴注射失敗。注射自動裝配依賴失敗（春季用SpringMVC + JPA + + springdata）
applicationContext.xml中：
<context:property-placeholder location="classpath:db.properties"/>
<bean id="dataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"></bean>
</property>
<property name="packagesToScan" value="com.luoxiao.sssp"></property>
<property name="jpaProperties">
<props>
<prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
</props>
</property>
<property name="sharedCacheMode" value="ENABLE_SELECTIVE"></property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"></property>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
<jpa:repositories base-package="com.luoxiao.sssp"
entity-manager-factory-ref="entityManagerFactory"></jpa:repositories>
springDispatcherServlet-servlet.xml中
<context:component-scan base-package="com.luoxiao.sssp" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
</context:component-scan>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<mvc:default-servlet-handler/>
<mvc:annotation-driven/>
存儲庫：
@Repository
public interface EmployeeRepository extends JpaRepository<Employee, Integer>{
}
服務：
@Service
public class EmployeeService {
@Autowired
public EmployeeRepository employeeRepository;
@Transactional
public Page<Employee> getPage(int pageNo,int pageSize){
PageRequest pageable = new PageRequest(pageNo-1, pageSize);
return employeeRepository.findAll(pageable);
}
}
處理程序：
@Controller
public class EmployeeHandler {
@Autowired
public EmployeeService employeeService;
@RequestMapping(value="/emps")
public String list(@RequestParam(value="pageNo",required = false,defaultValue="1")String pageNoStr,Map<String,Object>map){
int pageNo = 1;
try{
Integer.parseInt(pageNoStr);
}catch(Exception e){
Page<Employee> page = employeeService.getPage(pageNo, 5);
map.put("page", page);
}
return "emp/list";
}
} 例外：
