使用elastic-job出现的异常解决方案

<dependency>
    <groupId>com.dangdang</groupId>
    <artifactId>elastic-job-lite-spring</artifactId>
    <version>2.1.5</version>
</dependency>
<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
    <version>1.0.5-RELEASE</version>
</dependency>

环境：

jdk1.7+
spring3.1.0-RELEASE+
zookeeper3.4.6+

1.org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'zk-job-center'

org.apache.zookeeper包冲突 ;

解决方案：升级低版本的zookeeper包，注意其他包冲突（log4j，quartz）；

2.PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.RuntimeException: Failed to loa
d driver class com.mysql.jdbc.Driver in either of HikariConfig class loader or Thread context classloader

未引入mysql驱动包；

解决方案：

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>${mysql.version}</version>
</dependency>

3.java.sql.SQLNonTransientConnectionException: CLIENT_PLUGIN_AUTH is required

解决方案：使用mysql 6+版本的驱动包报异常，使用5.1.45版本正常

4.org.springframework.beans.factory.BeanCreationException:Error creating bean with name 'com.dangdang.ddframe.job.lite.spring.api.SpringJobScheduler#0': Invocation of init method failed; nested exception is java.lang.RuntimeException: CronExpression '0 10 0 ? * ? *' is invalid

解决方案：cron表达式错误，正确： 0 10 0 * * ?

5.java.text.ParseException: '?' can only be specfied for Day-of-Month -OR- Day-of-Week.

*：可用在所有字段中，表示对应时间域的每一个时刻，例如，*在分钟字段时，表示每分钟都会触发事件;

?：该字符只在日期和星期字段中使用；
