使用 JBoss 保险丝启动捆绑包时出现 BeanCreationException

Question

我创建了 maven 项目来将 rest web 服务暴露给 jboss fuse:

pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</build>

    <jaxrs:serviceBeans>
        <ref bean="employeeService" />
    </jaxrs:serviceBeans>
</jaxrs:server>

<bean id="employeeService" class="com.javainuse.beans.EmployeeServiceResource" />

EmployeeServiceResource.java

package com.javainuse.beans;
@Path("/")
public class EmployeeServiceResource {

public EmployeeServiceResource() {
}

@GET
@Path("/employees/{name}/")
public String getCustomer(@PathParam("name") String name) {
    return "Welcome " + name;
}

}

JBoss 熔断命令：

JBossFuse:karaf@root>安装mvn:com.javainuse/apache-camel-jaxrs/0.0.1-SNAPSHOT

捆绑包 ID：333

JBossFuse:karaf@root> START 333 -> 给我这个异常： org.springframework.beans.factory.BeanCreationException：创建名称为 'restService' 的 bean 时出错：bean 初始化失败；嵌套异常是 java.lang.NullPointerException

我正在使用 JBoss Fuse 6.3 和 java 1.8

Answer 1

您的 Maven POM 需要指定 bundle 作为打包类型：

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.javainuse</groupId>
    <artifactId>apache-camel-jaxrs</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>bundle</packaging>

    ...
</project>

Answer 2

我还注意到 jaxrs:server address="http://localhost:9000/employeeservice，这意味着你使用独立的 jetty 端口 9000。但是，当你部署到 FUSE 容器中时（Karaf/OSGi 基于），最佳实践是使用容器管理的 servlet 传输（默认端口 8181），因此请改用相对地址， address="/employeeservice" 然后您可以通过 http://localhost:8181/cxf/employeeservice
