spring boot 使用拦截器 无法注入 配置值 、bean问题

参考：https://www.cnblogs.com/SimonHu1993/p/8360701.html

 

一定要将 拦截器组件 交给spring容器进行管理，这样才能注入配置值，或者注入bean：

package com.thunisoft.maybeemanagementcenter.interceptor;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class WebAppConfigure extends WebMvcConfigurerAdapter {

    @Value("${thunisoft.microservice.mvc.interceptor.includePath:/**}")
    private String includePath;
    @Value("${thunisoft.microservice.mvc.interceptor.excludePath:/login/*}")
    private String excludePath;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        String[] excludePaths = excludePath.split(",");
        String[] includePaths = includePath.split(",");
        InterceptorRegistration ir = registry.addInterceptor(loginInterceptor())
                .addPathPatterns(includePaths)
                .excludePathPatterns(excludePaths);
        super.addInterceptors(registry);
    }

    @Bean
    public LoginInterceptor loginInterceptor() {
        return new LoginInterceptor();
    }
}

 

重点代码：

 

@Bean
    public LoginInterceptor loginInterceptor() {
        return new LoginInterceptor();
    }

 

 

registry.addInterceptor(loginInterceptor())
