異常記錄---Error creating bean with name 'sqlSessionFactory'

記錄幾種異常的處理方法：

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

 

原因是缺少spring-jdbc  jar包

引入依賴或jar包即可

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

2、異常報錯：An SQLException was provoked by the following failure: java.lang.InterruptedException

原因是沒引入mysql-connector-java的jar包，或是mysql-connector-java的版本問題，升級至與mysql版本一致即可。

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

3、springMVC開發web的時候，報錯：java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config

原因：未引入jstl包

pom.xml引入jstl，問題解決。

  <!-- 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使用的時候有時候會出現java.sql.SQLException: The server time zone value '???ú±ê×??±??' is unrecognized or represents........的錯誤，具體錯誤如下：

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.

 出現這個的原因是因為 mysql返回的時間總是有問題，比實際時間要早8小時。

解決辦法：

在url后面添加 serverTimezone=Asia/Shanghai ：

jdbc.url=jdbc:mysql://127.0.0.1:3306/caipiao?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
