It gives a detailed description on how to write -JSON based REST Web services and also Web service clients via JSON and Curl, how to -write a custom login, and how to use them in a token based Web service that also helps -prevent cross site scripting (XSS). -</p> -<a name="Introduction"></a> - -<h2>Introduction</h2> - -<p>This user guide is written based on the Axis2 Standard Binary -Distribution. The Standard Binary Distribution can be directly <a -href="../download.cgi">downloaded</a> or built using -the Source Distribution. If -you choose the latter, then the <a href="installationguide.html">Installation -Guide</a> will instruct you on how to build Axis2 Standard Binary -Distribution using the source.</p> - -<p>The source code for this guide provides a pom.xml for an entire demo application built by maven. -</p> - -<p>Please note that Axis2 is an open-source effort. If you feel the code -could use some new features or fixes, please get involved and lend us a hand! -The Axis developer community welcomes your participation.</p> - -<p>Let us know what you think! Send your feedback to "<a -href="mailto:java-u...@axis.apache.org?subject=[Axis2]">java-u...@axis.apache.org</a>". -(Subscription details are available on the <a href="../mail-lists.html">Axis2 site</a>.) Kindly -prefix the subject of the mail with [Axis2].</p> - -<h2>Getting Started</h2> - -<p>This user guide explains how to write and deploy a -new JSON and REST based Web Service using Axis2, and how to write a Web Service client -using JSON with Curl. -</p> - -<p>All the sample code mentioned in this guide is located in -the <b>"samples/userguide/src/springbootdemo"</b> directory of <a -href="../download.cgi">Axis2 standard binary -distribution</a>.</p> -<p> -This quide supplies a pom.xml for building an exploded WAR with Spring Boot - -however this WAR does not have an embedded web server such as Tomcat. -</p> -<p> -The testing was carried out on Wildfly, by installing the WAR in its app server. -</p> -<p>Please deploy the result of the maven build via 'mvn clean install', axis2-json-api.war, into your servlet container and ensure that it installs without any errors.</p> - -<h2>Creating a New Web Service</h2> - -<p> -Areas out of scope for this guide are JWT and JWE for token generation and validation, -since they require elliptic curve cryptography. A sample token that is not meant for -production is generated in this demo - with the intent that the following standards -should be used in its place. This demo merely shows a place to implement these -standards. -</p> -<p> -https://datatracker.ietf.org/doc/html/rfc7519 -https://datatracker.ietf.org/doc/html/rfc7516 -</p> -<p> -Tip: com.nimbusds is recommended as an open-source Java implementation of these -standards, for both token generation and validation. -</p> -<p> -DB operations are also out of scope. There is a minimal DAO layer for authentication. -Very limited credential validation is done. -</p> -<p> -The NoOpPasswordEncoder Spring class included in this guide is meant for demos -and testing only. Do not use this code as is in production. -</p> -<p> -This guide provides two JSON based web services, LoginService and TestwsService. -</p> -<p> -The login, if successful, will return a simple token not meant for anything beyond demos. -The intent of this guide is to show a place that the JWT and JWE standards can be -implemented. -</p> -<p> -Axis2 JSON support is via POJO Objects. LoginRequest and LoginResponse are coded in the LoginService as the names would indicate. -</p> -<p> -Also provided is a test service, TestwsService. It includes two POJO Objects as would -be expected, TestwsRequest and TestwsResponse. This service attempts to return -a String with some Javascript, that is HTML encoded by Axis2 and thereby -eliminating the possibility of a Javascript engine executing the response i.e. a -reflected XSS attack. -</p> -<p> -Concerning Spring Security and Spring Boot, the Axis2Application class that -extends SpringBootServletInitializer as typically done utilizes -List<SecurityFilterChain> as a binary choice; A login url will match, otherwise invoke -JWTAuthenticationFilter. All URL's to other services besides the login, will proceed -after JWTAuthenticationFilter verifies the token. -</p> -<p> -The JWTAuthenticationFilter class expects a token from the web services JSON client in -the form of "Authorization: Bearer mytoken". -</p> -<p> -The Axis2WebAppInitializer class supplied in this guide, is the config class -that registers AxisServlet with spring boot. -</p> -<p> -Axis2 web services are installed via a WEB-INF/services directory that contains -files with an .aar extention for each service. These aar files are similar to -jar files, and contain a services.xml that defines the web service behavior. -The pom.xml supplied in this guide generates these files. -</p> -<p> -Tip: don't expose methods in your web services that are not meant to be exposed, -such as getters and setters. Axis2 determines the avaliable methods by reflection. -For JSON, the message name at the start of the JSON received by the Axis2 server -defines the Axis2 operation to invoke. It is recommended that only one method per -class be exposed as a starting point. The place to add method exclusion is the -services.xml file: -</p> -<p> - <excludeOperations> - <operation>setMyVar</operation> - </excludeOperations> -</p> -<p> -The axis2.xml file can define Moshi or GSON as the JSON engine. GSON was the original -however development has largely ceased. Moshi is very similar and is widely considered -to be the superior implementation in terms of performance. GSON will likely continue to -be supported in Axis2 because it is helpful to have two JSON implementations to compare -with for debugging. -</p> -<p> -JSON based web services in the binary distribution of axis2.xml are not enabled by -default. See the supplied axis2.xml of this guide, and note the places were it has -"moshi". Just replace "moshi" with "gson" as a global search and replace to switch to -GSON. -</p> -<p> -Axis2 web services that are JSON based must be invoked from a client that sets an -HTTP header as "Content-Type: application/json". In order for axis2 to properly -handle JSON requests, this header behavior needs to be defined in the file -WEB-INF/conf/axis2.xml. -</p> -<p> - <messageFormatter contentType="application/json" - class="org.apache.axis2.json.moshi.JsonFormatter"/> -</p> -<p> -Other required classes for JSON in the axis2.xml file include JsonRpcMessageReceiver, -JsonInOnlyRPCMessageReceiver, JsonBuilder, and JSONMessageHandler. -</p> -<p> -Invoking the client for a login that returns a token can be done as follows: -</p> -<p> -curl -v -H "Content-Type: application/json" -X POST --data @/home/myuser/login.dat http://localhost:8080/axis2-json-api/services/loginService -</p> -<p> -Where the contents of /home/myuser/login.dat are: -</p> -<p> -{"doLogin":[{"arg0":{"email":java-...@axis.apache.org,"credentials":userguide}}]} -</p> -<p> -Response: -</p> -<p> -{"response":{"status":"OK","token":"95104Rn2I2oEATfuI90N","uuid":"99b92d7a-2799-4b20-b029-9fbd6108798a"}} -</p> -<p> -Invoking the client for a Test Service that validates a sample token can be done as -follows: -</p> -<p> -curl -v -H "Authorization: Bearer I2SpAHWrU5gYbGNwNNKg" -H "Content-Type: application/json" -X POST --data @/root/test.dat http://localhost:8080/axis2-json-api/services/testws' -</p> -<p> -Where the contents of /home/myuser/test.dat are: -</p> -<p> -{"doTestws":[{"arg0":{"messagein":hello}}]} -</p> -<p> -Response, HTML encoded to prevent XSS: -</p> -<p> -{"response":{"messageout":"<script xmlns=\"http://www.w3.org/1999/xhtml\">alert('Hello');</script> \">","status":"OK"}} -</p> -</body> -</html>
