spring bean对象request字段自动注入javax.servlet.ServletRequest

##spring bean对象request字段自动注入javax.servlet.ServletRequest

对象里面request全局变量是否线程安全呢？

答案:线程安全

##代码如下

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.ServletRequest;

@Controller
@RequestMapping("/mi")
public class YymController {

    public YymController() {
        System.out.println("yym");
    }

    @Autowired
    private ServletRequest request;

    @RequestMapping("/tomcatRequest")
    @ResponseBody
    public String tomcatRequest() {
        String yym = request.getParameter("yym");
        return yym;
    }

}

##源码

##和当前线程绑定，线程安全
