我有一个maven + spring + gwt(2.4.0)项目。当我运行mvn gwt:run时出现以下错误:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project star: Compilation failure: Compilation failure:

我的CDocumpentProxy.java看起来像是:
@ProxyFor(value = com.base.star.server.domain.CDocument.class, locator=
com.base.star.server.locators.customer.CDocumentLocator.class)
public interface CDocumentProxy extends EntityProxy {
byte[] getDocument(); //line 19
void setDocument(byte[] document); //line 21
如果我用STS 2.9.2构建项目,项目就会建立起来。所以我认为问题是maven-compiler-plugin配置错误。
在我的.pom文件中,我配置了maven-compiler-plugin,如:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
我不能将byte []用作请求工厂代理中方法的返回类型吗?我只是无法理解错误..
答案 0 :(得分:1)
您无法在请求工厂中使用数组:https://developers.google.com/web-toolkit/doc/latest/DevGuideRequestFactory#transportable
话虽如此,对于byte[]
等价物,我宁愿使用String
而不是List<Byte>
,GWT会为{1}}模拟UTF-8和ISO -8859-1 charsets。
