嗨专家,我有这个控制器代码,抛出上述错误.它工作正常,直到昨天,我不知道同事对此代码做了什么,今天我看到错误:

BindingResult和bean名称'sideForm'的普通目标对象都不可用作请求属性

你能告诉我在哪里寻找这种错误吗？我在POST或GET方法声明中犯了什么错误或者返回错误了吗？

非常感谢您的帮助:)

我正在尝试编写一个Spring MVC Web应用程序,用户可以在其中添加电影名称到内存中的集合.它的配置是这样的

public class Application extends AbstractAnnotationConfigDispatcherServletInitializer {
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] {};
    }
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { SpringServletConfig.class };
    }
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
}

和

@Configuration
@ComponentScan("com.example")
public class SpringServletConfig extends WebMvcConfigurationSupport {
    @Bean
    public InternalResourceViewResolver resolver() {
        InternalResourceViewResolver vr = new InternalResourceViewResolver();
        vr.setPrefix("WEB-INF/jsps/");
        vr.setSuffix(".jsp");
        return vr;
    }
}

有一个单一@Controller类在com.example包

@Controller
public class MovieController {
    private final CopyOnWriteArrayList<Movie> …
