Consider defining a bean of type 'com.situ.mall.admin.service.UserService' in your configuration.

To define a bean of type 'com.situ.mall.admin.service.UserService' in your configuration, you can use the @Bean annotation in Java configuration or the corresponding XML configuration.

In Java configuration, you can create a method annotated with @Bean that returns an instance of the UserService class. Here's an example:

@Configuration
public class AppConfig {

    @Bean
    public UserService userService() {
        return new UserService();
    }

}

In XML configuration, you can use the <bean> element to define the UserService bean. Here's an example:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="userService" class="com.situ.mall.admin.service.UserService"/>

</beans>

Make sure to replace "com.situ.mall.admin.service.UserService" with the actual package and class name of your UserService implementation.
