我试图配置到使用ehcache在春季启动时缓存，但是我遇到了一个错误的"org.springframework.beans.factory.parsing.BeanDefinitionParsingException:配置问题:无法为XML模式命名空间[http://www.ehcache.org/v3]定位spring NamespaceHandler“

我在“资源”文件夹中有一个名为ehcache.xml的配置文件，并将其添加到主类中，如

代码语言：javascript
复制
@SpringBootApplication
@ImportResource("classpath:ehcache.xml")
public class AirsoftwebApplication {

public static void main(String[] args) {         
    SpringApplication.run(AirsoftwebApplication.class, args);
}

}

我的配置

代码语言：javascript
复制
<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
        xmlns='http://www.ehcache.org/v3'
        xsi:schemaLocation='http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core.xsd'>

    <cache alias="users">
        <key-type>java.lang.Long</key-type>
        <value-type>com.perunsmillstone.model.entities.User</value-type>
        <expiry>
            <ttl>10</ttl>
        </expiry>
        <resources>
            <offheap unit="MB">150</offheap>
        </resources>
    </cache>
</config>

缓存配置java类

代码语言：javascript
复制
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableCaching
public class CachingConfig {
}

在EHcache中设置Spring Boot的通常方法是在application.xml中使用该属性：

代码语言：javascript
复制
spring.cache.jcache.config=classpath:ehcache.xml

来源：https://docs.spring.io/spring-boot/docs/2.1.7.RELEASE/reference/htmlsingle/#boot-features-caching-provider-jcache

我已经在几个项目中使用过它，并且从未通过导入配置文件作为资源来配置它。
