Question

我们将一个上下文文件放在 CATALINA_BASE / conf / localhost / MyApp.xml。

的位置

MyApp.XML的内容如下。

    <?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/MyApp">>
    <Resource 
        auth="Container" 
        driverClassName="oracle.jdbc.OracleDriver" 
        name="jdbc/MyApp_local" 
        password="XXXX" 
        type="javax.sql.DataSource" 
        url="XXXX" 
        username="XXX"
        factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
        initialSize="10"
        maxWait="-1"
        maxActive="55"
        maxIdle="21"
        minIdle="13"
        timeBetweenEvictionRunsMillis="34000"
        minEvictableIdleTimeMillis="55000"
        validationQuery="SELECT 1"
        validationInterval="34"
        testOnBorrow="true"
        removeAbandoned="true"
        removeAbandonedTimeout="233"
    />
    <Resource 
        auth="Container" 
        driverClassName="oracle.jdbc.OracleDriver" 
        name="jdbc/MyApp_local_du" 
        password="XXX" 
        username="XXXX"
        type="javax.sql.DataSource" 
        url="XXX" 
        factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
        initialSize="5"
        maxWait="-1"
        maxActive="55"
        maxIdle="21"
        minIdle="13"
        timeBetweenEvictionRunsMillis="34000"
        minEvictableIdleTimeMillis="55000"
        validationQuery="SELECT 1"
        validationInterval="34"
        testOnBorrow="true"
        removeAbandoned="true"
        removeAbandonedTimeout="233"
    />
</Context>

was文件已复制到 CATALINA_BASE / webapps / MyApp.war

启动应用程序时未正确创建数据源，因为我在日志中可以看到以下错误。

        ... 33 common frames omitted

我认为应用程序无法正确解析JNDI。奇怪的是我没有在我的本地tomcat中得到这个错误。仅当部署到unix环境时才会出现此问题。知道为什么没有检测到上下文。

Tomcat 7从conf / Catalina / localhost加载Context XML
