wsdl2 java :Java 堆空间

Question

我正在使用网络服务。我有一个文件 wdsl 并将其转换为两个 java 文件：

wsdl2java -uri nameFile.wsdl

创建的 java 文件之一有 87kb。当我尝试用 eclipse 打开它时，出现以下错误：

java.lang.OutOfMemoryError: Java heap space

我现在想如果：

1) 参数 wsdl2java 出现问题。这意味着可以通过某种方式创建更多 java 文件而不是大文件。

2）eclipse内存问题

如何解决？

谢谢

Answer 1

尝试增加 eclipse 的 xss 和 xmx 吗？
编辑 eclipse.ini 文件并添加/更改以下参数：
-Xmx512m

您还可以尝试在“文本编辑器”中打开它：在 eclipse 中右键单击您的文件 -> 使用文本编辑器打开。

Answer 2

尝试在 wsdl2java 上使用 -u 标志。

-u             Unpacks the databinding classes
