【问题描述】：

我想使用 terracotta + Shiro 来实现 SSO。当我尝试对其进行测试时，出现错误：

    The configuration data in the base configuration from server at 'localhost:9510' does not obey the Terracotta schema:
    [0]: Line 4, column 5: Expected elements 'tc-properties servers clients' instead of 'system' here in element tc-config@http://www.terracotta.org/config
    [1]: Line 16, column 13: Expected elements 'offheap authentication http-authentication data-backup tsa-port jmx-port tsa-group-port security' instead of 'statistics' here in element server

    [7]: Line 86, column 5: Element not allowed: application in element tc-config@http://www.terracotta.org/config

谁能帮我找出问题所在？

这是我的配置：

tc客户端上的ehcache.xml：

<ehcache  name="Plugin_Ehcache"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="ehcache.xsd"
     updateCheck="false" monitoring="autodetect"
     dynamicConfig="false">

        eternal="false"

        overflowToDisk="false"
        diskPersistent="false"
        diskExpiryThreadIntervalSeconds="120">

【解决方案1】：

您使用的是哪个版本的 Terracotta 库？ tc-config.xml 在 4.x 版本以后有一些更新的标签。请确保 tc-config 和 ehcache xml 遵循架构。

我看到你试图在你的 tc 配置中使用 mirror-group 标记，但似乎你放错了位置。

例如，这个配置应该可以工作：

<?xml version="1.0" encoding="UTF-8" ?>
<tc:tc-config xsi:schemaLocation="http://www.terracotta.org/schema/terracotta-8.xsd"
              xmlns:tc="http://www.terracotta.org/config"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <tc-properties>
    <property name="l2.l1reconnect.enabled" value="true"/>
    <property name="l2.l1reconnect.timeout.millis" value="5000"/>
    <property name="sigar.enabled" value="false"/>
    <property name="search.use.commit.thread" value="false"/>
    <property name="search.lucene.use.ram.directory" value="true"/>
    <property name="search.query.wait.for.txns" value="false"/>
    <property name="logging.maxLogFileSize" value="100"/>
    <property name="logging.maxBackups" value="10"/>
  </tc-properties>

  <servers>
    <mirror-group group-name="group1">
      <server host="localhost" name="Terracotta Server1">
        <!-- Specify the path where the server should store its data. -->
        <data>C:\Program Files\Terracotta\terracotta-3.7.5\server\server-data</data>
        <logs>C:\Program Files\Terracotta\terracotta-3.7.5\server\server-logs</logs>
        <index>C:\Program Files\Terracotta\terracotta-3.7.5\server\server-index</index>
        <!--<statistics>C:\Program Files\Terracotta\terracotta-3.7.5\server\server-statistics</statistics>-->

        <!-- Specify the port where the server should listen for client
        traffic. -->
        <tsa-port>9510</tsa-port>
        <jmx-port>9520</jmx-port>
        <tsa-group-port>9530</tsa-group-port>

        <authentication/>

      </server>
    </mirror-group>

    <update-check>
      <enabled>false</enabled>
    </update-check>

    <!-- Add the restartable element for Fast Restartability (optional). -->
    <!--restartable enabled="true"/-->
  </servers>
  <clients>
    <logs>logs-%i</logs>
  </clients>
</tc:tc-config>

【解决方案3】：

查看定义用于构建 xml 配置文件的架构的这一行：

<tc:tc-config xsi:schemaLocation="http://www.terracotta.org/schema/terracotta-8.xsd

输入提供的地址，看看嵌套的xml元素和属性是如何被允许使用的。

例如，在 terracotta-6.xsd 和 terracotta-7.xsd 中允许元素 dso-port，但在您声明的 terracotta-8.xsd 中不允许。

顺便说一句，根据您使用的 terracotta 服务器版本，由于元素不兼容，应声明适当的 xml 架构。
