我吉斯配置看起来像：吉斯，JerseyServletModule，为法缺失的依赖，REST服务配置
public class SocialServiceGuiceConfig extends GuiceServletContextListener {
@Override
protected Injector getInjector() {
final Module [] modules = {
new JerseyServletModule() {
@Override
protected void configureServlets() {
bind(GraphApi.class);
bind(SocialUncheckedExceptionMapper.class).in(Singleton.class);
bind(SocialUnhandledExceptionMapper.class).in(Singleton.class);
serve("/*").with(
GuiceContainer.class);
}
},
};
return Guice.createInjector(modules);
}
}
我的API定义看起来是这样的：
@Path("/{" + BUSINESS_CUSTOMER_PARAMETER + "}")
public BusinessCustomerApi businessCustomerAndContext(
@PathParam(BUSINESS_CUSTOMER_PARAMETER) final BusinessCustomerPathParam businessCustomerPathParam,
@QueryParam(LOCALE_PARAMETER) final String locale) {
我在得到异常我的日志：

为什么会发生这种情况？在网上很难找到信息，并且无法弄清楚什么路径可以徘徊。
