Jax-rs Development (III): cross-domain issues when Ajax accesses rest services

The same-origin policy means that the protocol, host, and Port are the same. We can deploy 2 different ports of Tomcat on the local machine so that one Tomcat app accesses the rest service under another tomcat through Ajax, so there is a cross-domain access problem. Modify the three port numbers below the Conf/server.xml:

<server port= "* * * *" shutdown= "shutdown" >    <connector port= "* * *" protocol=               "http/1.1" connectiontimeout= "20000"               redirectport= "8443"/>    <connector port= "* * *" protocol= "ajp/1.3" redirectport= "8443"/>

On the basis of the previous blog, in order to solve the CXF cross-domain problem needs:

1. Modify pom file to increase providers

<dependency><groupid>org.apache.cxf</groupid><artifactid>cxf-rt-rs-extension-providers </artifactId><version>${cxf.version}</version></dependency>

2. Modify the Cxf-spring.xml Configuration Jsonp Interceptor

<?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:jaxrs= "Http://cxf.apache.org/jaxrs" xsi:schemalocation= " http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/ Spring-beans-3.0.xsdhttp://cxf.apache.org/jaxrshttp://cxf.apache.org/schemas/jaxrs.xsd "><jaxrs:server address= "/rest" ><jaxrs:servicebeans><ref bean= "Nameserviceimpl"/></jaxrs:servicebeans>< !--Jsonp--><jaxrs:providers><bean class= " Org.apache.cxf.jaxrs.provider.jsonp.JsonpPreStreamInterceptor "/&GT;&LT;/JAXRS:PROVIDERS&GT;&LT;JAXRS: Ininterceptors><bean class= "Org.apache.cxf.jaxrs.provider.jsonp.JsonpInInterceptor"/&GT;&LT;/JAXRS: Ininterceptors><jaxrs:outinterceptors><bean class= " Org.apache.cxf.jaxrs.provider.jsonp.JsonpPostStreamInterceptor "/&GT;&LT;/JAXRS:OUTINTERCEPTORS&GT;&LT;/JAXRS: Server></beans>

3. Access via Ajax under another tomcat

$.ajax ({  type: ' Get ',  URL: ' http://127.0.0.1:8080/aty-rest/rest/rest/welcome ',  dataType: ' Jsonp ',  jsonp: ' _jsonp ',  jsonpcallback: ' Callback ',  success:function (data) {alert (json.stringify (data);  }});

This article refers to the Web service Thing (4)-a good introductory article using CXF to develop rest services.
