异常记录---Error creating bean with name 'sqlSessionFactory'

Posted 2022-04-27 jsoso

记录几种异常的处理方法：

1、
Error creating bean with name ‘sqlSessionFactory‘ defined in class path resource [applicationContext-dao.xml]: Error
setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested
PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property ‘dataSource‘ threw exception; nested
exception is java.lang.NoClassDefFoundError: org/springframework/jdbc/datasource/TransactionAwareDataSourceProxy

 

在maven工程下  Junit测试  dao 层报错,  原因是缺少spring-jdbc  jar包

引入依赖即可

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>

2、异常报错：An SQLException was provoked by the following failure: java.lang.InterruptedException

原因是没引入mysql-connector-java的jar包，或是mysql-connector-java的版本问题，升级至与mysql版本一致即可。

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.13</version>
</dependency>

3、springMVC开发web的时候，报错：java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config

原因：未引入jstl包

pom.xml引入jstl，问题解决。

  <!-- java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config -->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>

4、在JDBC使用的时候有时候会出现java.sql.SQLException: The server time zone value ‘???ú±ê×??±??‘ is unrecognized or represents........的错误，具体错误如下：

Loading class `com.mysql.jdbc.Driver‘. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver‘. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

 出现这个的原因是因为 mysql返回的时间总是有问题，比实际时间要早8小时。

解决办法：

jdbc.url = jdbc:mysql://localhost:3306/jdbc01?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false

 在jdbc连接的url后面加上serverTimezone=GMT即可解决问题，如果需要使用gmt+8时区，需要写成GMT%2B8，问题就会解决；
