I'm hoping someone on this list can help me figuring out what I'm missing. I'm trying to write a CXF/Spring/JAX-RS webapp that uses JSON for both inputs and outputs. I've got a simple ICalculator interface with the standard add/subtract/multiply/divide methods. add/subtract are working used @PathParm and @QueryParam annotations and return valid JSON responses for the CalculatorResponse class. I've been trying to get multiply (or divide) to work by posting a JSON string that has the parameters. In essence, I'd like the following request to parse and pass parameters appropriately:
POST /calculator/multiply HTTP/1.1 Accept: */* Accept-Language: en-us Referer: http://server/jaxrstest/calc.html x-requested-with: XMLHttpRequest Content-Type: application/json Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) Host: server:80 Content-Length: 18 Connection: Keep-Alive Pragma: no-cache { "x":20, "y":10 } But CXF always complains because the parser for the input isn't parsing JSON. It sees the '{' character and throws an exception because it was expecting a number. I've searched google and the cxf-users list but haven't found an example that tells me how to configure CXF to parse the JSON string. Has anyone tried doing this? I'm hoping I just missed a setting in the Spring Config files. Using cxf-bundle-jaxrs 2.2.2, spring 2.5.6 Relevant code/config files below: @XmlRootElement( name="CalculatorResponse" ) public class CalculatorResponse { double m_value; // Default Constructor public CalculatorResponse() { } public void setValue( double value ) { m_value = value; } public double getValue() { return m_value; } } @Path("/calculator/") @Consumes("application/json") @Produces("application/json") public interface ICalculator { /** * This will be accessible via /calculator/1/2 * @param x value for x * @param y value for y * @return CalculatorResponse */ @GET @Path("/add/{x}/{y}") CalculatorResponse add( @PathParam( "x" )long x, @PathParam( "y" )long y ); /** * The parameters here will be passed like typical URL params * /calculator/subtract?x=10.0&y=5.0 * @param x Value for X * @param y Value for Y * @return CalculatorResponse */ @GET @POST @Path("subtract") CalculatorResponse subtract( @QueryParam( "x" ) double x, @QueryParam( "y" ) double y ); @POST @Path("divide") CalculatorResponse divide( double x, double y ); @POST @Path("multiply") CalculatorResponse multiply( double x, double y ); } public class CalculatorImpl implements ICalculator { // Default Constructor public CalculatorImpl() { } public CalculatorResponse add( long x, long y) { CalculatorResponse response = new CalculatorResponse(); response.setValue( x+y ); return response; } public CalculatorResponse subtract( double x, double y) { CalculatorResponse response = new CalculatorResponse(); response.setValue( x-y ); return response; } public CalculatorResponse divide( double x, double y) { CalculatorResponse response = new CalculatorResponse(); response.setValue( x/y ); return response; } public CalculatorResponse multiply( double x, double y) { CalculatorResponse response = new CalculatorResponse(); response.setValue( x*y ); return response; } } <?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"; xmlns:util="http://www.springframework.org/schema/util"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd"; default-lazy-init="false"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <util:map id="jsonNamespaceMap" map-class="java.util.Hashtable"> <entry key="http://databasin.org/"; value="b"/> <entry key="http://cxf.apache.org/bindings/xformat"; value="cxf" /> </util:map> <bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.JSONProvider"> <property name="namespaceMap" ref="jsonNamespaceMap"/> </bean> <bean id="calculatorBean" class="com.esri.solutions.databasin.impl.CalculatorImpl" /> <jaxrs:server id="myService" address="/"> <jaxrs:serviceBeans> <ref bean="calculatorBean" /> </jaxrs:serviceBeans> <jaxrs:providers> <ref bean="jsonProvider" /> </jaxrs:providers> </jaxrs:server> </beans> --- Javier Delgadillo ESRI / Implementation Services http://www.arcwebservices.com/ (909) 793-2853 x1068
