在单个应用程序服务器中部署多个Saiku应用程序：REST冲突

Question

在GlassFish应用程序服务器中部署了一个Saiku实例。

休息后端：saiku 前端：saiku-ui

所以，我提出以下要求：

http://external_ip_here/saiku-ui/

然后我通过授权，创建我需要的OLAP多维数据集，一切正常。

当我尝试在同一个应用程序服务器中安装另一个Saiku实例时，问题就开始了，但是在另一个域中（让我们说domain）。

我将前端部分和其余后端重命名如下：

休息后端：saiku-enterprise 前端：analytic-ui

因此，JavaScript和URL映射中的所有Ajax调用都从/saiku/替换为/saiku-enterprise/

applicationContext-saiku-enterprise.xml（最初名为applicationContext-saiku-webapp.xml）：

<security:http auto-config='true' access-denied-page="/login.jsp">
<security:intercept-url pattern="/serverdocs/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<security:intercept-url pattern="/rest/saiku/session*" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<security:intercept-url pattern="/rest/saiku/session/" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<security:intercept-url pattern="/rest/**" access="IS_AUTHENTICATED_FULLY" />
<security:intercept-url pattern="/json/**" access="IS_AUTHENTICATED_FULLY" />
<security:intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />  
<security:logout logout-url="/logout"/>  
<security:http-basic/>

</security:http>
<import resource="applicationContext-spring-security.xml"/>

web.xml的一部分：

...
<servlet>
   <servlet-name>jersey2</servlet-name>
   <servlet-class>org.codehaus.enunciate.modules.jersey.EnunciateJerseyServletContainer</servlet-class>
   <init-param>
      <param-name>com.sun.jersey.config.property.packages</param-name>
      <param-value>org.saiku.web</param-value>
   </init-param>
   <init-param>
      <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
      <param-value>com.sun.jersey.api.container.filter.PostReplaceFilter</param-value>
   </init-param>
   <init-param>
      <param-name>org.codehaus.enunciate.modules.jersey.config.ServletPath</param-name>
      <param-value>/rest</param-value>
   </init-param>
   <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
   <servlet-name>jersey2</servlet-name>
   <url-pattern>/rest/saiku/*</url-pattern>
</servlet-mapping>

<servlet-mapping>
   <servlet-name>jersey2</servlet-name>
   <url-pattern>/rest/saiku/session</url-pattern>
</servlet-mapping>
...

我重新加载了一个新的Saiku实例（只需在文件\domain\applications\saiku-enterprise\.reload中进行更改 - 之后Saiku会自动重启）

接下来我提出请求：

http://external_ip_here/analytic-ui/

并收到错误（我可以在FifeBug或Google Chrome控制台中看到它）：

HTTP Status 404: http://external_ip_here/saiku-enterprise/rest/saiku/session?_=1414754157176

因此，Saiku的新实例不起作用。

在工作配置中（不重命名），此资源可用：

/saiku/rest/saiku/session?_=1414761814333

如果在客户端我指定BASE_URL == http://127.0.0.1:8080，如下所示：

/**
 * Change settings here
 */
var Settings = {
    VERSION: "Saiku 2.5",
    BIPLUGIN: false,
    BASE_URL: "http://127.0.0.1:8080",
    TOMCAT_WEBAPP: "/saiku-enterprise",
    REST_MOUNT_POINT: "/rest/saiku/",
    DIMENSION_PREFETCH: true,
    ERROR_LOGGING: false,
    // number of erroneous ajax calls in a row before UI cant recover
    ERROR_TOLERANCE: 3,
    QUERY_PROPERTIES: {
        'saiku.olap.query.automatic_execution': 'true',
        'saiku.olap.query.nonempty': 'true',
        'saiku.olap.query.nonempty.rows': 'true',
        'saiku.olap.query.nonempty.columns': 'true',
        'saiku.ui.render.mode' : 'table'
    },
    /* Valid values for CELLSET_FORMATTER:
     * 1) flattened
     * 2) flat
     */
    CELLSET_FORMATTER: "flattened",
    // limits the number of rows in the result
    // 0 - no limit
    RESULT_LIMIT: 0,
    MEMBERS_FROM_RESULT: true,
    PLUGINS: [
        "Chart"
    ],
    TELEMETRY_SERVER: 'http://telemetry.analytical-labs.com:7000',
    LOCALSTORAGE_EXPIRATION: 10 * 60 * 60 * 1000 /* 10 hours, in ms */
};

然后我收到此错误：

Aborted: http://external_ip_here/analytic-ui/

应用程序开始无休止地重新加载..

为了链接前端和后端，我添加了两个bean as recommended：

<bean id="platformBean" class="org.saiku.service.PlatformUtilsService">
    <property name="path" value="../../../docroot/analytic-ui/js/saiku/plugins/"/>
</bean>

<bean id="infoResource" class="org.saiku.web.rest.resources.InfoResource">
    <property name="platformUtilsService" ref="platformBean"/>
</bean>

但它没有帮助。

同样的错误：

HTTP Status 404: http://external_ip_here/saiku-enterprise/rest/saiku/session?_=14...

可能是什么问题？我非常感谢这些信息。谢谢大家。

Answer 1

我明白了。在静态资源中，应对文件Settings.js进行更改，如下所示：

/**
 * Change settings here
 */
var Settings = {
    VERSION: "Saiku 2.5",
    BIPLUGIN: false,
    BASE_URL: "",
    TOMCAT_WEBAPP: "/saiku-enterprise",
    REST_MOUNT_POINT: "/rest/saiku/",
    DIMENSION_PREFETCH: true,
    ERROR_LOGGING: true,
    // number of erroneous ajax calls in a row before UI cant recover
    ERROR_TOLERANCE: 3,
    QUERY_PROPERTIES: {
        'saiku.olap.query.automatic_execution': 'true',
        'saiku.olap.query.nonempty': 'true',
        'saiku.olap.query.nonempty.rows': 'true',
        'saiku.olap.query.nonempty.columns': 'true',
        'saiku.ui.render.mode' : 'table'
    },
    /* Valid values for CELLSET_FORMATTER:
     * 1) flattened
     * 2) flat
     */
    CELLSET_FORMATTER: "flattened",
    // limits the number of rows in the result
    // 0 - no limit
    RESULT_LIMIT: 0,
    MEMBERS_FROM_RESULT: true,
    PLUGINS: [
        "Chart"
    ],
    TELEMETRY_SERVER: 'http://telemetry.analytical-labs.com:7000',
    LOCALSTORAGE_EXPIRATION: 10 * 60 * 60 * 1000 /* 10 hours, in ms */
};

即指定适当的上下文 - 前端必须指向正确的休息后端。

TOMCAT_WEBAPP: "/saiku-enterprise",

不需要在其他地方进行更改（如果您使用它，则除applicationContext-spring-security-jdbc.xml之外）。

现在一切都好。
