尝试方法引用类方法时“方法引用中的不兼容参数类型”
尝试方法引用类方法时“方法引用中的不兼容参数类型”
提问于 2022-08-10 07:49:31
我试图模拟TemplateRendererUtil类的静态方法TemplateRendererUtil，以便在测试时返回null。不确定这是否是正确的方法，我试图测试的方法调用这个类，但我只想让它跳过这个类。
在这里获得一个编译错误：
try (MockedStatic<TemplateRendererUtil> mockedStatic = Mockito.mockStatic(TemplateRendererUtil.class)){
// java: incompatible types: incompatible parameter types in method reference
mockedStatic.when(TemplateRendererUtil::render).thenReturn(null);
}被引用的类：
public class TemplateRendererUtil {
private static final ResponseTemplateRenderer RENDERER = ResponseTemplateRenderer.getInstance();
private TemplateRendererUtil() {
}
public static void render(HttpServletRequest req, HttpServletResponse resp, String templateFile, Map<String, Object> params) throws TemplateRendererUtilException {
try {
RENDERER.render(req, resp, templateFile, params);
} catch (ResponseTemplateRendererException var5) {
throw new TemplateRendererUtilException(var5);
}
}

如我所见，render方法不会返回任何内容，因此可以这样做。
try (MockedStatic<TemplateRendererUtil> mockedStatic = Mockito.mockStatic(TemplateRendererUtil.class)){
doNothing().when(TemplateRendererUtil.render(Mockito.any(), Mockito.any(), Mockito.anyString(), Mockito.anyMap()));
