应用上下文文件是

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

<context:component-scan base-package="com.mtv.rest" />
<bean id="transactionBo"
class="com.mtv.rest.TransactionBoImpl" />
</beans>
支付类
package com.mtv.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.mtv.rest.TransactionBo;
@Component
@Path("/payment")
public class PaymentService {
@Autowired
TransactionBo transactionBo;
@GET
@Path("/mtv")
public Response savePayment() {
String result = transactionBo.save();
return Response.status(200).entity(result).build();
}
}
界面是
package com.mtv.rest;
public class TransactionBoImpl implements TransactionBo {
public String save() {
return "Jersey + Spring example";
}
}
有时tomcat端口也会出错.
also sometimes tomcat port gets error.
