Spring Boot Rest服务表单太大
我正在使用Spring Boot" title="Spring Boot">Spring Boot 1.3.2,需要公开REST
Web服务。对于此Web服务,我需要传递一个String(包含xml数据)作为参数。字符串的大小通常在2 MB到120
MB之间。问题是我不知道如何配置REST方法参数允许的最大大小,并且默认大小太小。由于其他依赖性,Spring配置必须在Java类中。这是我的配置类:
@Configuration@ComponentScan("eu.buzea")
@EnableAutoConfiguration
@EnableNeo4jRepositories("eu.buzea.datamodel.repositories")
@EnableTransactionManagement
@SpringBootApplication
public class Application extends Neo4jConfiguration {
public Application() {
System.setProperty("username", <CONFIDENTIAL>);
System.setProperty("password", <CONFIDENTIAL>);
}
@Override
public Neo4jServer neo4jServer() {
return new RemoteServer("http://localhost:7474");
}
@Override
public SessionFactory getSessionFactory() {
return new SessionFactory("eu.buzea.datamodel.entities");
}
@Override
@Bean
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
return super.getSession();
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
这是我的网络方法的样子:
@RequestMapping(method = RequestMethod.POST)public boolean processing(@RequestParam(value = "xml", required = true) String xml)
当我向该方法发送字符串时,出现以下错误:

谁能告诉我如何将最大表单内容大小( 最大请求大小 )设置为200 MB或无限?
我想设置 maxFormContentSize 参数,但是不确定是Eclipse参数还是Spring参数。
PS我现在知道如何使用MultipartFile Upload解决问题。另外,还有另一个选择:在请求正文中发送字符串/数据。它们都很 好用
,但是我想知道是否可以在Spring或Eclipse中设置 maxFormContentSize
回答:
Spring Boot 1.4.0.M2具有一个新属性,server.max-http-post-
size可用于配置此属性。里程碑可从https://repo.spring.io/libs-
milestone获得。
如果您想坚持使用Spring Boot 1.3.x,可以通过将以下bean添加到应用程序的配置中来自己实现相同的逻辑:
@Beanpublic EmbeddedServletContainerCustomizer jettyCustomizer() {
return new EmbeddedServletContainerCustomizer() {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
if (container instanceof JettyEmbeddedServletContainerFactory) {
((JettyEmbeddedServletContainerFactory) container)
.addServerCustomizers(new JettyServerCustomizer() {
@Override
public void customize(Server server) {
setHandlerMaxHttpPostSize(200 * 1024 * 1024, server.getHandlers());
}
private void setHandlerMaxHttpPostSize(int maxHttpPostSize,
Handler... handlers) {
for (Handler handler : handlers) {
if (handler instanceof ContextHandler) {
((ContextHandler) handler)
.setMaxFormContentSize(maxHttpPostSize);
}
else if (handler instanceof HandlerWrapper) {
setHandlerMaxHttpPostSize(maxHttpPostSize,
((HandlerWrapper) handler).getHandler());
}
else if (handler instanceof HandlerCollection) {
setHandlerMaxHttpPostSize(maxHttpPostSize,
((HandlerCollection) handler).getHandlers());
}
}
}
});
}
}
};
}
