java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map

本文主要是介绍java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Spring Boot整合Camunda，使用feigin调用Camunda REST API 时失败

首先，pom.xml中有下面三个引用

       <dependency>
           <groupId>org.camunda.bpm.springboot</groupId>
           <artifactId>camunda-bpm-spring-boot-starter-rest</artifactId>
           <version>${camunda.spring-boot.version}</version>
       </dependency>

       <dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

       <dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>

其次、执行提交流程请求，调用Camunda 的启动流程REST API，结果返回异常

curl -X POST "http://localhost:8080/simpleRestProcessHandler/simpleStartProcess" -H "accept: */*" -H "crctoken: crctoken#000" -H "Content-Type: application/json" -d "{ \"processDefId\": \"\", \"processDefKey\": \"Process_3201\", \"startProcessInstanceDto\": { \"businessKey\": \"CamRest201903291\", \"variables\": { \"starter\": { \"type\": \"string\", \"value\": \"bx1\", \"valueInfo\": {} }, \"assignee020\": { \"type\": \"string\", \"value\": \"bx2\", \"valueInfo\": {} }, \"assignee030\": { \"type\": \"string\", \"value\": \"bx3\", \"valueInfo\": {} } }, \"withVariablesInReturn\": false }, \"starter\": \"bx1\", \"title\": \"CamRest201903291\"}"

异常信息如下：

使用javax.ws.rs过滤pom的依赖结构，可以发现camunda使用的jersey里边有对java.ws.rs-api:2.1的引用，eureka里边有对jsr311-api:1.1.1的应用，也就是类冲突导致异常，只需要将eureka里边的jsr311-api排除即可。

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<exclusions>
               <exclusion>
                   <groupId>javax.ws.rs</groupId>
                   <artifactId>jsr311-api</artifactId>
               </exclusion>
           </exclusions>
</dependency>

修复后，重新提交正常
