Receiver class com.mchange.v2.c3p0.impl.NewProxyResultSet does not define

问题原因是 c3p0的配置不正确

之前的配置

<dependency>
            <groupId>c3p0</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.1.2</version>
        </dependency>

改为下面的配置

<dependency>
      <groupId>com.mchange</groupId>
      <artifactId>c3p0</artifactId>
      <version>0.9.5.5</version>
    </dependency>
