Question

我正在尝试在Spring Boot中使用现有的Spring Security xml文件。我加了 @ImportResource加载我现有的xml配置。在控制台上，其显示正在加载spring-security.xml。

我遇到以下错误：

 "Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.security.servlet.SpringBootWebSecurityConfiguration$DefaultConfigurerAdapter': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.security.config.annotation.ObjectPostProcessor<?>' available"

***************************
APPLICATION FAILED TO START

Description:

A component required a bean of type 'org.springframework.security.config.annotation.ObjectPostProcessor' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.security.config.annotation.ObjectPostProcessor' in your

OnlineshoppingApplication.java

package net.kzn.onlineshopping;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ComponentScan(basePackages = {"net.kzn.onlineshopping","net.kzn.shoppingbackend"})
@ImportResource({"classpath:spring-security.xml","classpath:dispatcher-servlet.xml"})
public class OnlineshoppingApplication {

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


}

spring-security.xml

我该如何解决这个问题？

Answer 1

我建议您共享pom.xml文件，并尝试将以下注释与springboot应用程序一起使用，因为缺少一些内容。

根据您的设置，如果遇到与启动自动配置有关的任何启动错误，则可能必须排除一些自动配置类，例如通过将其放入您的Application类：

@EnableAutoConfiguration(exclude = [SecurityFilterAutoConfiguration, SpringBootWebSecurityConfiguration])

还使用spring-boot添加@EnableWebSecurity注释。

如何在Spring Boot中使用spring-security.xml中的配置？
