Consider defining a bean of type 'wzl.user_center.mapper.UserMapper' in your configuration.

这个错误提示是因为Spring Boot在启动时无法找到UserMapper的bean定义。解决这个问题的方法是在配置类中添加对UserMapper的bean定义。
以下是解决方法的示例代码:
```java
@Configuration
public class MybatisConfig {
@Bean
public UserMapper userMapper() {
return new UserMapper();
}
}
```
在上述代码中,我们使用`@Configuration`注解标记了一个配置类,并在该类中定义了一个名为`userMapper`的bean,返回类型为`UserMapper`。这样,Spring Boot在启动时就能找到并创建UserMapper的实例。

Consider defining a bean of type 'com.lvxin.mapper.UserMapper' in your configuration
To define a bean of type 'com.lvxin.mapper.UserMapper' in your configuration, you can use the `@Bean` annotation in Java or the `@Component` annotation in Spring.
Here's an example using `@Bean` annotation:
```java
@Configuration
public class AppConfig {
@Bean
public UserMapper userMapper() {
return new UserMapper();
}
}
```
In this example, the `UserMapper` bean is defined and can be injected into other beans or components.
Alternatively, you can use the `@Component` annotation to define the `UserMapper` bean:
```java
@Component
public class UserMapper {
// bean implementation
}
```
With this approach, Spring will automatically scan and register the `UserMapper` bean in your application context.
Remember to replace `com.lvxin.mapper.UserMapper` with the actual package and class name of your `UserMapper` interface or class.
Consider defining a bean of type 'com.wms.mapper.UserMapper' in your configuration.
To define a bean of type 'com.wms.mapper.UserMapper' in your configuration, you can use the `@Bean` annotation along with the `@Configuration` annotation in a Java configuration class. Here's an example:
```java
@Configuration
public class AppConfig {
@Bean
public UserMapper userMapper() {
return new UserMapper();
}
}
```
Make sure to replace `UserMapper` with the actual implementation of the `com.wms.mapper.UserMapper` interface or class. This configuration class will create a bean of type `UserMapper` that can be used throughout your application.
Additionally, ensure that the `com.wms.mapper.UserMapper` class is available in your classpath and properly configured.
