在Spring Web应用程序中找不到类[org.springframework.scheduling.quartz.SchedulerFactoryBean]

标签： java spring quartz-scheduler

我正在尝试在Spring的Web应用程序中构建调度程序。我使用Maven处理所有依赖项。我将以下bean放入了XML 

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="configLocation" value="classpath:quartz.properties" />
</bean>

在web.xml文件中，我有以下内容（来自教程）：

<context-param>
     <param-name>quartz:config-file</param-name>
     <param-value>quartz.properties</param-value>
 </context-param>
 <context-param>
     <param-name>quartz:shutdown-on-unload</param-name>
     <param-value>true</param-value>
 </context-param>
 <context-param>
     <param-name>quartz:wait-on-shutdown</param-name>
     <param-value>false</param-value>
 </context-param>
 <context-param>
     <param-name>quartz:start-scheduler-on-load</param-name>
     <param-value>true</param-value>
 </context-param>

在pom.xml中，我再次添加了教程建议

    <!-- Quartz API -->
    <dependency>
        <groupId>opensymphony</groupId>
        <artifactId>quartz</artifactId>
        <version>1.6.3</version>
    </dependency>

    <dependency>
        <groupId>commons-collections</groupId>
        <artifactId>commons-collections</artifactId>
        <version>3.2.1</version>
    </dependency>

    <dependency>
        <groupId>org.apache.directory.studio</groupId>
        <artifactId>org.apache.commons.logging</artifactId>
        <version>1.1.1</version>
    </dependency>

    <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.2.1</version>
    </dependency>

    <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz-jobs</artifactId>
        <version>2.2.0</version>
    </dependency>

我还定义了quartz.properties文件

org.quartz.plugin.jobInitializer.class = 
org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz_jobs.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 10
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

当然还有我的crystal_jobs.xml文件：

<?xml version='1.0' encoding='utf-8'?>
<job-scheduling-data xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.quartz- 
scheduler.org/xml/JobSchedulingData http://www.quartz- 
scheduler.org/xml/job_scheduling_data_1_8.xsd"
  version="1.8">

<schedule>
    <job>
        <name>myJob</name>
        <group>MYJOB_GROUP</group>

        <description>My job description</description>
        <job-class>com.blah.blah.myJob</job-class>

    </job>

    <trigger>
        <cron>
            <name>myTrigger</name>
            <group>MYTRIGGER_GROUP</group>
            <job-name>myJob</job-name>

            <job-group>MYJOB_GROUP</job-group>
            <!-- trigger every 5 seconds -->
            <cron-expression>0/5 * * * * ?</cron-expression>

        </cron>
    </trigger>
</schedule>

然后，我创建了一个调度程序和一个作业类（类似于基础教程的类）。我的问题是，当我运行它时，我会收到3个错误：

2018-09-10 14:52:23,636 - ERROR - [org.springframework.web.context.ContextLoader] - Context initialization failed

SEVERE: Exception sending context initialized event to listener instance of class org.quartz.ee.servlet.QuartzInitializerListener
java.lang.NoClassDefFoundError: javax/transaction/UserTransaction

更多日志记录后，它显示Quartz Scheduler successful shutdown.。我不知道发生了什么，我对所做的事情没有超级的信心，因为我并不真正了解Java spring及其配置。有人可以找出我想念的东西吗？

编辑：通过在我的pom.xml中添加javax.transaction解决了第三个错误

EDIT2：这是完整的堆栈跟踪：

由于消息显示，您错过了类路径中的javax.trasaction API：

java.lang.NoClassDefFoundError: javax/transaction/UserTransaction

添加

<!-- https://mvnrepository.com/artifact/javax.transaction/javax.transaction-api -->
<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>javax.transaction-api</artifactId>
    <version>1.3</version>
</dependency>

作为依赖项和异常应该解决。

另一个问题是缺少类org.springframework.scheduling.quartz.SchedulerFactoryBean

也添加

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>${spring.version}</version>
</dependency>
