springmvc 实现文件下载 出现异常java.lang.OutOfMemoryError: Java heap space

网上找解决方案,一般都是tomcat中添加-Xms256m -Xms512m等配置,但是不行啊。
我的是MyEclipse里的tomcat。
下载20M(包括)以内的文件没问题,超过就会报异常,有什么解决办法吗?
还有是不是请求下载文件时,服务器会把文件全部装入内存再发过来,还是分成多个部分发送,超过内存大小的文件如何发送呢?

请求下载文件时,服务器会把文件的字节数据写入请求响应中即Socket的OutputStream中,本质上也应该是在内存中的,如果文件过大,而你的代码处理时又是一次读取完成的话,就可能会报堆内存溢出异常了。
你的文件下载使用的是控件吗,如果是自己写的下载代码的话,可以优化不要一次读取完成,而是分批读取避免堆内存溢出。

springmvc下servlet.init()异常
web.xml里servlet配置 <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> springmvc-servlet.xml下扫描路径: <context:component-scan base-package="com.shuai.moudle.teacher.controller"></context:component-scan> 路径是存在的,一访问控制器就出错,报这个错可能是什么原因?应该能排除jdk和spring 版本问题,因为我其他项目不会出这个错误 下面错误详情: 严重: StandardWrapper.Throwable

springMvc 返回json数据报错!
环境:springMvc5.1.8 jackson-databind2.9.9 ``` @Controller public class EmployeeController { @Autowired private EmployeeService employeeService; @RequestMapping(value = "/emps") @ResponseBody public

converter found for return value of type: class java.util.ArrayList。 通过百度,找到解决方法,在applicationContext.xml中添加如下内容: ``` <mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter"/> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/> </mvc:message-converters>

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

Python实例大全(基于Python3.7.4)
博客说明: 这是自己写的有关python语言的一篇综合博客。 只作为知识广度和编程技巧学习,不过于追究学习深度,点到即止、会用即可。 主要是基础语句,如三大控制语句(顺序、分支、循环),随机数的生成,数据类型的区分和使用; 也会涉及常用的算法和数据结构,以及面试题相关经验; 主体部分是针对python的数据挖掘和数据分析,主要先攻爬虫方向:正则表达式匹配,常用数据清洗办法,scrapy及其他爬虫框架,数据存储方式及其实现; 最后还会粗略涉及人工智能领域,玩转大数据与云计算、进行相关的预测和分析。
