smartGWT中的行分隔符的java等价物？

Question

是否有一个等效的或替代的

System.getProperty("line.separator");

它给出了以下错误

类型系统中的方法getProperty（String，String）不适用于参数（String）

Answer 1

我认为您需要在服务器端代码中执行System.getProperty("line.separator")，并使用RPC或任何其他服务器端gwt通信技术访问它

勾选GWT JRE Emulation：

GWT includes a library that emulates a subset of the Java runtime library. The list below shows the set of JRE packages, types and methods that GWT can translate automatically. Note that in some cases, only a subset of methods is supported for a given type.

System

err, out
System(), arraycopy(Object, int, Object, int, int), currentTimeMillis(), gc(), getProperty(String, String), identityHashCode(Object), setErr(PrintStream), setOut(PrintStream)
