今天继续《OSGi原理与最佳实践》。看到第四章。做 HelloWorld-cxf 的样例

照着样例敲来着,整个样例敲完了,执行。一直报错,

----------------这里是解决方法------------------

	Dictionary<String, String> props = new Hashtable<String, String>();

        props.put("osgi.remote.interfaces", "*");
props.put("osgi.remote.configuration.type", "pojo");
props.put("osgi.remote.configuration.pojo.address", "http://localhost:9000/hello_world"); registration = bundleContext.registerService(HelloWorldServiceInterfaces.class.getName(),
new HelloWorldImple(), props);

把上面的内容改成以下

	Dictionary<String, String> props = new Hashtable<String, String>();

        <span style="color:#ff0000;">props.put("service.exported.interfaces", "*");
props.put("service.exported.configs", "org.apache.cxf.ws");
props.put("org.apache.cxf.ws.address", "http://localhost:9000/hello_world");</span> registration = bundleContext.registerService(HelloWorldServiceInterfaces.class.getName(),
new HelloWorldImple(), props);

bundle配置例如以下,我没有单独到处servlet和osgi,直接用的eclipse里面的

---------------以下是故事。能够不看-------------------

不行,复制原来的代码直接贴过去(网上找的资源)还是一样。

各种缺包的提示。尝试着加入各种bundle。最后都要吐来了。还是提示缺。并且是越来越缺,全然一个无底洞。一定那里出问题了。

删除项目又一次建,还好,这次不提示缺包了,这让我想起了,上一篇里面提到的,有可能是bundle以来问题,应该简单操作一下即可了,详细操作请查看

http://blog.csdn.net/q821424508/article/details/46604279

言归正传,说下今天的问题。

把项目弄好之后启动项目。没有错误提示,訪问的时候抱404错误,控制台提示httpservice startup at 8080 ,这事什么意思,我代码里不是这么写的

	Dictionary<String, String> props = new Hashtable<String, String>();

        props.put("osgi.remote.interfaces", "*");
props.put("osgi.remote.configuration.type", "pojo");
props.put("osgi.remote.configuration.pojo.address", "http://localhost:9000/hello_world"); registration = bundleContext.registerService(HelloWorldServiceInterfaces.class.getName(),
new HelloWorldImple(), props);

这问题就来了。启动不报错。可是訪问不到路径。一定还是那里配置错误,

亲,没错的,代码都是复制过来的。那问题可有可能是版本号的问题,我的环境。cxf插件下载的事最新的cxf-dosgi-ri-singlebundle-distribution-1.2.jar,

osgi也是比书里面的新,

别问我为什么不依照书里面的版本号弄。我也想。仅仅是有些资源时找不到的。所以就依照自己eclipse的默认版本号来了。

说到版本号不同,那就找下官网吧。

Service Provider properties For Configuring SOAP-based services and consumers

Note: for backwards compatibility old values marked below are still supported.

Property Name

Data Type

Example

Description

service.exported.interfaces

(previously:osgi.remote.interfaces)

String

org.example.BarService,org.example.FooService*

Denotes the interfaces to be exposed remotely. This is a comma-separated list of fully qualified Java interfaces that should be made available remotely. A special value of * can be provided meaning that all of the interfaces passed to
the BundleContext.registerService() call are suitable for remoting.

service.exported.configs (previously:osgi.remote.configuration.type)

String

org.apache.cxf.ws

Specifies the mechanism for configuring the service exposure. Possible values:

  • org.apache.cxf.ws (previously: pojo) the OSGi Service is exposed as a Web Service.
  • wsdl configuration driven from WSDL

这个事官网的,

Note: for backwards compatibility old values marked below are still supported.

这句翻译过来,应该是为了兼容老的功能,以下呗标记出来的依旧支持吧,高中水平。不知道是不是这么翻译的。

可是依照翻译来说,我依照书上敲(别扣字眼。是复制来的我知道)的代码应该没问题

继续看

org.apache.cxf.ws configuration type

When the service.exported.configs=org.apache.cxf.ws (or osgi.remote.configuration.type=pojo) property is specified, the following properties may also be specified.

突然来了一句,这句的大概意思是 假设service.exported.configs=org.apache.cxf.ws (or osgi.remote.configuration.type=pojo)
这个被指定了,

那么以下的也必须被设置,

我仅仅能呵呵了 。

Property Name

Data Type

Example

Description

org.apache.cxf.ws.address

(previously:osgi.remote.configuration.pojo.address)

String

{{

http://localhost:9090/greeter

}}

The address at which the service with be made available remotely. If this property is not specified, this defaults to {{

http://localhost:9000/fully/qualified/ClassName

}}.

org.apache.cxf.ws.httpservice.context

(previously:osgi.remote.configuration.pojo.httpservice.context)

String

/auction

When this property is specified, the OSGi HTTP Service is used to expose the service, rather than a dedicated Jetty HTTP Server. This property doesn't allow the specification of a port number, as this is provided by the HTTP Service. The Distributed OSGi distributions
come with Pax-Web, for which configuration information can be found here:

http://wiki.ops4j.org/display/paxweb/Configuration

, however other OSGi HTTP Service implementations are potentially configured differently.

org.apache.cxf.ws.frontend

String

jaxws

The CXF frontend which will be used to create endpoints. Defaults to 'simple' which is an Aegis-based simple frontend. Note that for JAXWS to work a javax.jws.* has to be imported into the interface and/or implementation and client bundles for annotations like
@WebService and @WebMethod be recognized

org.apache.cxf.ws.databinding

String

jaxb

Supported values are 'aegis and 'jaxb', defaults to 'aegis'. Note that for JAXB to work JAXB packages like javax.xml.bind.annotation.* have to be imported

org.apache.cxf.ws.wsdl.service.ns

String

{{

http://services.org

}}

org.apache.cxf.rs configuration type

When the service.exported.configs=org.apache.cxf.rs property is specified, the following properties may also be specified.

Property Name

Data Type

Example

Description

org.apache.cxf.rs.address

String

{{

http://localhost:9090/greeter

}}

The address at which the service with be made available remotely. If this property is not specified, this defaults to {{

http://localhost:9000/fully/qualified/ClassName

}}.

org.apache.cxf.rs.httpservice.context

String

/auction

When this property is specified, the OSGi HTTP Service which is used to expose the service, rather than a dedicated Jetty HTTP Server. By default, absolute address may look like 'http://localhost:8080/auction'

org.apache.cxf.rs.provider.globalquery

Boolean

true/false

Can be used to disable queries for global providers, defaults to 'true'.

org.apache.cxf.rs.databinding

String

aegis

This property has a limited value for JAXRS services as JAXB is supported by default, the only supported value is 'aegis' and it is a shortcut for registering an Aegis provider, see below for more information on how to register custom providers for JAXRS services

org.apache.cxf.rs.wadl.location

String

/wadl/service.wadl

这么多,怎么设。算了。用最新的吧

	Dictionary<String, String> props = new Hashtable<String, String>();

        props.put("service.exported.interfaces", "*");
props.put("service.exported.configs", "org.apache.cxf.ws");
props.put("org.apache.cxf.ws.address", "http://localhost:9000/hello_world"); registration = bundleContext.registerService(HelloWorldServiceInterfaces.class.getName(),
new HelloWorldImple(), props);

最新版的java代码是这种,

能执行,能訪问了。

我还是想吐糟一下。明明说要向下兼容,为什么要设置那么多额外的属性。
