我无法在CustomerServiceImpl服务类中的引用变量中注入customerDao对象.
这是我的mule_flow.mflow文件

这是我的CustomerServiceImpl.java
package com.proj.pos.webservice.implementation;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;
import com.proj.pos.dao.interfac.CustomerDao;
import com.proj.pos.entity.Customer;
import com.proj.pos.webservice.interfac.CustomerService;
@WebService(endpointInterface = "com.proj.pos.webservice.interfac.CustomerService",
serviceName = "CustomerService")
public class CustomerServiceImpl implements CustomerService {
public CustomerDao getCustomerDao() {
return customerDao;
}
public void setCustomerDao(CustomerDao customerDao) {
this.customerDao = customerDao;
}
@Autowired
private CustomerDao customerDao;//not getting populated.tried removing autowired as well.
@Transactional
@WebMethod(operationName="addCustomer")
@WebResult(name="addCustomerResult")
@Override
public Customer addCustomer(@WebParam(name="customerId")long customerId,@WebParam(name="fname")String fname,@WebParam(name="lname")String lname,@WebParam(name="age")long age,@WebParam(name="dateOfBirth")String dateOfBirth,@WebParam(name="address")String address) {
Customer customer=new Customer(customerId, fname, lname, age, dateOfBirth, address);
customer.setCustomerId(customerDao.persist(customer));//throws NUllPointerException here as customerDao is null..
return customer;
}
}
知道DI不工作的原因吗？
解决方法:
你可能遗漏了几件事：
>您应该扫描您想要弹簧的包,以查看带注释的类.在您的情况下,您应该将以下xml片段添加到您的mule配置< context：component-scan base-package =“com.proj.pos.webservice”/>
>您应该将组件声明为spring对象而不是组件,因此应该替换< component class =“com.proj.pos.webservice.implementation.CustomerServiceImpl”
doc：name =“Java”/>与< component>< spring-object bean =“customerService”/>< / component>
