admin

因为 jdk 是1.8的版本，和 dubbo-admin 存在兼容性问题。所以报错：

Bean property 'URIType' is not writable or has an invalid

参见：https://github.com/alibaba/dubbo/issues/50

解决方法，修改 tomcat 默认的 jdk到 1.7 :

1) 修改bin文件夹下面的catalina.bat文件，把如下内容
rem ----- Execute The Requested Command ----------------------------------
echo Using CATALINA_BASE: %CATALINA_BASE% 
echo Using CATALINA_HOME: %CATALINA_HOME% 
echo Using CATALINA_TMPDIR: %CATALINA_TMPDIR% 
echo Using JAVA_HOME: %JAVA_HOME% 

修改为：
echo Using CATALINA_BASE: %CATALINA_BASE% 
echo Using CATALINA_HOME: %CATALINA_HOME% 
echo Using CATALINA_TMPDIR: %CATALINA_TMPDIR% 
echo Using JAVA_HOME: D:\Java\jdk1.7.0_79

2) 修改bin文件夹下面的setclasspath.bat文件，把如下内容： 
rem Set standard command for invoking Java. 

rem Note that NT requires a window name argument when using start. 
rem Also note the quoting as JAVA_HOME may contain spaces. 
set _RUNJAVA="%JAVA_HOME%\bin\java" 
set _RUNJAVAW="%JAVA_HOME%\bin\javaw" 
set _RUNJDB="%JAVA_HOME%\bin\jdb" 
set _RUNJAVAC="%JAVA_HOME%\bin\javac" 

修改为: 
rem Set standard command for invoking Java. 

rem Note that NT requires a window name argument when using start. 
rem Also note the quoting as JAVA_HOME may contain spaces. 
set _RUNJAVA="D:\Java\jdk1.7.0_79\bin\java.exe"

set _RUNJDB="D:\Java\jdk1.7.0_79\bin\jdb.exe"

然后在使用 startup.bat 启动成功：

当然还有其他解决方法。参见 https://github.com/alibaba/dubbo/issues/50

访问控制台：

dubbo 报错：Failed to read schema document 'http://code.alibabatech.com/schema/dubbo/dubbo.xsd'问题解决方法

注意上面的 Location 的路径中不能含义 '.' 字符和 '-' 字符开头的目录，不然报错：

具体原理可以参考：

http://blog.csdn.net/gaoshanliushui2009/article/details/50469595

 

dubbo-admin的搭建还是十分简单的。基本只要修改一下 dubbo.properties 就行了：

dubbo.registry.address=zookeeper://192.168.1.4:2181
dubbo.admin.root.password=xxxx
dubbo.admin.guest.password=xxxxx
