JBoss AS 7部署顺序和时序

Question

我这里有一个问题,一般是部署顺序,特别是时间.

我有一个耳朵1,通过bean和一些队列提供一些功能.队列在standalone.xml中配置.另一个耳朵2使用来自ear1的这项服务.

所以依赖关系看起来像:ear1 < - ear2

因此,我将耳2的部署结构配置为依赖于耳1,现在部署顺序本身是正确的.

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="deployment.ear1.ear" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

部署顺序现在是正确的,但我现在拥有的是竞争条件,因为(我猜)未初始化的bean来自耳朵1.

当我延迟部署ear2时,一切正常.

有谁知道如何控制部署的时间.是否可以通过jboss-deployment-structure.xml指定部署顺序,还可以指定开始下一次部署所需的生命周期？

UPDATE

我试图指定包含要使用的服务的实际bean jar.这也行不通.看起来像:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="deployment.ear1.ear.bean.jar" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

Answer 1

正如您现在可能知道的那样,将在JBoss 7.2中引入耳内依赖性.
一个EAR定义了其他EAR使用的服务,我遇到了同样的问题.我通过在standalone.xml中完全关闭自动部署来解决这个问题:

    <subsystem xmlns="urn:jboss:domain:deployment-scanner:1.1">
        <deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000" auto-deploy-zipped="false" auto-deploy-exploded="false"/>
    </subsystem>

并在启动JBoss之前在单独的线程中运行以下脚本.该脚本创建部署列表,并使用JBoss 7部署扫描程序标记文件按指定顺序部署它们.即它为第一次部署创建.dodeploy标记,然后等待它部署,然后为第二次部署创建.dodeploy标记等.

#!/bin/bash
function contains() {
    local n=$#
    local value=${!n}
    for ((i=1;i < $#;i++)) {
        if [ "${!i}" == "${value}" ]; then
            echo "y"
            return 0
        fi
    }
    echo "n"
    return 1
}

    if [ $(contains "${APPS_ORDER[@]}" $APP) == "n" ]; then
        APPS_ORDER=("${APPS_ORDER[@]}" "$APP")
    fi
