我正在尝试向我的其余网络服务发送一组大字符串。该字符串包含 base64 图像(每个图像大小约为 4MB)。
我正在使用 tomcat7，根据 tomcat 文档，我将 maxPostSize 设置为 0 以禁用限制帖子大小(我也尝试设置 15mb 但没有任何变化)这是我的配置:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
URIEncoding="UTF-8"
redirectPort="8443"
maxPostSize="0" />
这是我的参数休息界面:
@RequestParam(required = true, value = "idSurvey") Long idSurvey,
@RequestParam(required = false, value = "address") String address,
@RequestParam(required = false, value = "picturesBase64") String[] picturesBase64

如果我发送小图像，一切正常。 有什么想法吗？
最佳答案
您需要增加堆大小，对于 tomcat 可以这样做
export CATALINA_OPTS=-Xms16m -Xmx2G;//change it as per your requriments
关于java - 将大字符串数组(base64 图像)发送到休息服务给出错误(使用 tomcat7)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27997574/
