问题描述

原始配置文件

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">
    <!-- this is the object that will be proxied by Spring's AOP infrastructure -->
    <bean id="personService" class="DefaultPersonService"/>
    <!-- this is the actual advice itself -->
    <bean id="profiler" class="SimpleProfiler"/>
    <aop:config>
        <aop:aspect ref="profiler">
            <aop:pointcut id="SomePersonServiceMethod"
                          expression="execution(* getPerson(String)) and args(name)"/>
            <aop:before pointcut-ref="SomePersonServiceMethod"
                        method="profile"/>
        </aop:aspect>
    </aop:config>
</beans>

上文来自于spring官方文档，目前希望采用 expression="execution(* DefaultPersonService.getPerson(..))来实现，但是一直报错说参数未能绑定，请问应该如何解决

运行环境

interllij开发版2021.3
jdk1.8
spring 5
该项目为基于maven的spring项目

文件代码补充

public class Person {
    private String name;
    public Person(String name) {
        this.name = name;
    }
    // the usual getters and setters...
}
public class DefaultPersonService {
    public Person getPerson(String name) {
        return new Person(name);
    }
}
public class SimpleProfiler {
    public void profile(String name) throws Throwable {
        System.out.println("Profiling for '" + name + "' and '" );
    }
}
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Boot {
    public static void main(final String[] args) throws Exception {
        BeanFactory ctx = new ClassPathXmlApplicationContext("beans.xml");
        DefaultPersonService person = (DefaultPersonService) ctx.getBean("personService");
        person.getPerson("Pengo");
    }
}

回答：

execution(* getPerson(String)) and args(name) 无法找到class吧
