spring mvc 框架
jerry 服务器
pom.xml添加（貌似要7以上的版本）

<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-servlets</artifactId>
<version>${jetty.version}</version>
</dependency>
web.xml
添加

<filter>
<filter-name>cross-origin</filter-name>
<filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
<init-param>
<param-name>allowedOrigins</param-name>
<param-value>*</param-value>
</init-param>
<init-param>
<param-name>allowedMethods</param-name>
<param-value>GET,POST,HEAD</param-value>
</init-param>
<init-param>
<param-name>allowedHeaders</param-name>
<param-value>X-Requested-With,Content-Type,Accept,Origin</param-value>
</init-param>

<init-param>
<param-name>allowCredentials</param-name>
<param-value>true</param-value>
</init-param>

</filter>
<filter-mapping>
<filter-name>cross-origin</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

添加过滤器
import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Component;

@Component("cors")
public class CorsFilter implements Filter {

@Override
public void init(FilterConfig filterConfig) throws ServletException {
//To change body of implemented methods use File | Settings | File Templates.
}

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;
httpResponse.addHeader("Access-Control-Allow-Origin", "*");
httpResponse.addHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept");
filterChain.doFilter(servletRequest, servletResponse);
}

@Override
public void destroy() {
//To change body of implemented methods use File | Settings | File Templates.
}

}

web.xml
<filter>
<filter-name>cors</filter-name>
<filter-class>com.*****.app.wap.common.filter.CorsFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>cors</filter-name>
<url-pattern>/*</url-pattern>

</filter-mapping>

开始还试了下吧spring 3.2.5升级到了4.2.5

报错了

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
       <property name="messageConverters">
           <list>
               <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                   <property name="supportedMediaTypes">
                       <list>
                           <value>text/plain;charset=UTF-8</value>
                       </list>
                   </property>
               </bean>
               <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
           </list>
       </property>
   </bean>

这个类没有了。。。。。

org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

变成了 org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

改了之后还是不可以

又找了大半天

<bean id="stringConverter"
        class="org.springframework.http.converter.StringHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/plain;charset=UTF-8</value>
            </list>
        </property>
    </bean>
   <bean id="jsonConverter"
       class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
   <bean
       class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
       <property name="messageConverters">
           <list>
               <ref bean="stringConverter" />
               <ref bean="jsonConverter" />
           </list>
       </property>
   </bean>

还要引用几个新的jar包

<groupId>com.fasterxml.jackson.core</groupId>
       <artifactId>jackson-databind</artifactId>
          <version>2.6.3</version></dependency>
          <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-core</artifactId>
           <version>2.6.3</version></dependency>
           <dependency>
           <groupId>com.fasterxml.jackson.core</groupId>
           <artifactId>jackson-annotations</artifactId>
          <version>2.6.3</version>
          </dependency>

总数是没有报错了
