/E:/javaweb(idea)/springcould/hmall/hm-api/src/main/java/com/hm/api/intercept/UserInfoIntercept.java:[4,30] 程序包com.hmall.common.utils不存在
时间: 2023-11-12 08:08:22 浏览: 49
这个错误提示表明程序无法找到com.hmall.common.utils这个包,可能是因为该包不存在或者没有被正确引入。你可以尝试以下几个方法来解决这个问题:
1. 确认该包是否存在于项目中,如果不存在,可以手动创建该包并将相关文件放入其中。
2. 确认该包是否被正确引入,可以检查pom.xml文件中是否有该包的依赖项,并且确认该依赖项是否被正确下载。
3. 如果以上两个方法都无法解决问题,可以尝试在IDE中重新导入项目或者清除项目缓存并重新构建项目。

No suitable driver found for jdbc:mysql//localhost:3306/,javaweb
This error message usually occurs when the JDBC driver for MySQL is not found or not properly configured in your Java application. To fix this issue, you need to make sure that you have the correct JDBC driver for MySQL installed and that the driver is included in your application's classpath.
Here are some steps you can follow to resolve this issue:
1. Download the JDBC driver for MySQL from the official website:
https://dev.mysql.com/downloads/connector/j/
2. Extract the downloaded ZIP file and copy the JAR file to a folder in your project directory.
3. Add the JDBC driver JAR file to your project's classpath. You can do this by adding the following line to your project's build file (e.g. pom.xml for Maven):
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.23</version>
</dependency>
4. Make sure that you are using the correct JDBC URL for your MySQL database. The format should be like this:
jdbc:mysql://localhost:3306/your_database_name
Replace "your_database_name" with the actual name of your MySQL database.
5. Check that your MySQL database is running and accessible from your Java application. You can test this by using a MySQL client tool (e.g. MySQL Workbench) to connect to the database using the same credentials that your Java application is using.
Once you have verified that the JDBC driver is installed and configured correctly, and that your MySQL database is running and accessible, you should be able to connect to the database from your Java application without any issues.
javaweb请求的资源[/contactSys_war_exploded/login]不可用
根据提供的引用内容,问题可能是由于在IDEA中运行Tomcat时,应用程序的上下文根被设置为“xxx_war_exploded”,而不是默认的“/”。因此,当您尝试访问http://localhost:8080/时,您会收到404错误,因为没有与根路径匹配的资源。要解决这个问题,您需要使用正确的上下文根来访问您的应用程序。
您可以尝试使用http://localhost:8080/xxx_war_exploded/login来访问您的应用程序,其中“xxx_war_exploded”是您的应用程序的上下文根。如果这个URL可以正常工作,那么您可以在IDEA中更改上下文根,以便您可以使用http://localhost:8080/来访问您的应用程序。
您可以按照以下步骤更改上下文根:
1. 在IDEA中打开您的项目。
2. 单击“运行”菜单,然后单击“编辑配置”。
3. 在“服务器”选项卡上,找到您的Tomcat服务器,并单击“配置”按钮。
4. 在“部署”选项卡上,找到您的应用程序,并将上下文根更改为“/”。
5. 单击“应用”按钮,然后单击“确定”按钮。
6. 重新启动Tomcat服务器,并尝试使用http://localhost:8080/来访问您的应用程序。
