Could not resolve placeholder 'iot.hiMallAddress.url' in value "${iot.hiMallAddress.url}"

您遇到的这个错误信息通常出现在使用Spring框架进行Java开发的应用程序中，特别是在配置文件（如application.properties或application.yml）中使用了占位符，但Spring无法找到对应的值时。这里的`iot.hiMallAddress.url`是一个占位符，而`${iot.hiMallAddress.url}`表示要将其替换为实际的配置值。当Spring在运行时尝试解析这个占位符，但没有找到相应的配置项时，就会抛出这个错误。

要解决这个问题，您可以按照以下步骤进行检查和修正：

1. 确认在配置文件中是否正确设置了`iot.hiMallAddress.url`的值。例如，如果您使用的是`application.properties`文件，则应该有如下配置：

   iot.hiMallAddress.url=http://example.com

2. 检查是否有拼写错误，配置项的名称是否完全匹配。例如，如果配置项实际上应该是`iot.hiMall.url`而不是`iot.hiMallAddress.url`，那么Spring就无法找到正确的值。

3. 如果您使用的是多环境配置文件（如application-dev.properties、application-prod.properties等），确保您当前激活的环境配置文件中包含了相应的配置项。

4. 检查应用程序是否正确加载了配置文件。有时可能是因为配置文件未被正确加载或存在多个配置文件冲突导致的问题。

Could not resolve placeholder 'spring.datasource.oracle.url' in value

This error message is typically seen in a Spring application when a placeholder is not properly resolved. In this case, the placeholder 'spring.datasource.oracle.url' is not being resolved correctly.

To resolve this issue, make sure that the property 'spring.datasource.oracle.url' is defined in your application's configuration file (e.g. application.yml or application.properties) and that its value is properly set. Additionally, make sure that your application is correctly configured to read properties from the configuration file.

For example, in application.yml, you might have:

spring:
  datasource:
    oracle:
      url: jdbc:oracle:thin:@//localhost:1521/orcl
      username: myuser
      password: mypassword

If you are using Spring Boot, you can also check that your application is correctly configured to use the appropriate configuration file. By default, Spring Boot looks for an application.yml or application.properties file in the classpath. If your configuration file is named differently or located in a different directory, you will need to specify this in your application's configuration or command line arguments.

Could not resolve placeholder 'us.ch.time.diff.hour' in value "${us.ch.time.diff.hour}"

This error message indicates that Spring could not find a value for the placeholder 'us.ch.time.diff.hour' in your configuration files.

To resolve this issue, check your configuration files and make sure that you have defined a value for this placeholder. You may also want to check that the configuration files are being loaded correctly by Spring.

If you are still having trouble, double-check the syntax of the placeholder to make sure it matches the syntax used in your configuration files.
