java-Spring Boot Rest服务表单太大

2023-07-17 07:59:04

我正在使用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(最大请求大小)最大表单内容大小设置为200 MB或无限大？

更新
以下文章提供了一个解决方案,以防您使用的是未安装在Spring Boot中的码头服务器：*.com/questions/3861455/form-too-large-exception

我想设置maxFormContentSize参数,但是不确定是Eclipse参数还是Spring参数.

附言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

解决方法:

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.里程碑从https://repo.spring.io/libs-milestone开始可用.

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：

@Bean
public 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());
                            }
                        }
                    }
                });
            }
        }
    };
}
