Spring MVC XML-less 配置异常：需要 ServletContext 来配置默认的 servlet 处理
Spring MVC XML-less configuration exception : A ServletContext is required to configure default servlet handling
我是 Spring 框架的新手，正在尝试 Spring MVC xml-less（没有 web.xml 或 mvc-dispatcher-servlet.xml) 配置，因为这是项目所需的。
当我尝试 运行 它时出现以下错误（使用 Jetty Local，再次是项目要求）
以下是我用于替换 web.xml:
的配置
（也试过扩展 AbstractAnnotationConfigDispatcherServletInitializer 但运气不好）
public class WebConfig implements WebApplicationInitializer {
@Override
public void onStartup( ServletContext servletContext ) throws ServletException {
WebApplicationContext rootContext = getContext(servletContext);
servletContext.addListener(new ContextLoaderListener(rootContext));
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("mvc", new DispatcherServlet(rootContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
private AnnotationConfigWebApplicationContext getContext(ServletContext ctx) {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
//Tried various combination of un/commenting following options.
context.register( MvcServletConfig.class );
//context.setConfigLocation("com.xyz.myapp.configuration");
context.setServletContext( ctx );
//context.refresh();
//context.scan( "com.xyz.someapp.*" );
return context;
}
}
这是我的 MVC/Servlet 配置替换 mvc-dispatcher-servlet.xml:
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = {"com.xyz.myapp"})
public class MvcServletConfig extends WebMvcConfigurerAdapter {
public MvcServletConfig() { super(); }

这是我的 AppConfig：

添加了 class 以在我的上下文刷新后立即初始化我的数据库，如下所示：
@Component
public class DbInitialiserOnStartUp implements ApplicationListener<ContextRefreshedEvent> {
@Autowired
private AccountService accountService;
@Transactional
@Override
public void onApplicationEvent( ContextRefreshedEvent contextRefreshedEvent ) {
if ( accountService != null )
{
//inserts etc...
}
}
}
我测试了它，它工作正常...试试这个：
// You named it WebConfig
public class WebAppInitializer implements WebApplicationInitializer { // web.xml replacement
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
// Here you need to change "io.shido.config" to your config location
applicationContext.setConfigLocation("io.shido.config");
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher",
new DispatcherServlet(applicationContext)); // Register and map the dispatcher servlet
//servletContext.setInitParameter("spring.profiles.default", "development");
servletContext.addListener(new ContextLoaderListener(applicationContext));
//applicationContext.register(AppConfig.class); // Manage the lifecycle of the root application context
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/web/*"); // ...and here also change the context
}
}
请注意，我也在使用 /web 作为我的上下文...因此请相应地更改它。有示例项目 here in case you want to take a look; and this 是 ZeroTurnaround 家伙写的关于该主题的非常非常好的文章。
此外，我的 Maven POM 文件中有：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<!--<packagingExcludes>WEB-INF/web.xml</packagingExcludes>-->

您的 Spring 配置工作正常（但您确实可以进一步改进它）；当您呼叫 HibernateConfig.InitialiseDummyData(); 时，问题出在 LoginController 线上。评论那一行，一切都会好起来的。
调用该方法时，您正在启动另一个 Spring 上下文。我无法修复数据库的问题，因为我没有您的架构...在进行 概念验证 时最好使用内存数据库。尝试 improve/fix 那段代码，你应该可以开始了。

if ( accountService != null )
{
//inserts etc...
}
}
}
我测试了它，它工作正常...试试这个：
// You named it WebConfig
public class WebAppInitializer implements WebApplicationInitializer { // web.xml replacement
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
// Here you need to change "io.shido.config" to your config location
applicationContext.setConfigLocation("io.shido.config");
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher",
new DispatcherServlet(applicationContext)); // Register and map the dispatcher servlet
//servletContext.setInitParameter("spring.profiles.default", "development");
servletContext.addListener(new ContextLoaderListener(applicationContext));
//applicationContext.register(AppConfig.class); // Manage the lifecycle of the root application context
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/web/*"); // ...and here also change the context
}
}
请注意，我也在使用 /web 作为我的上下文...因此请相应地更改它。有示例项目 here in case you want to take a look; and this 是 ZeroTurnaround 家伙写的关于该主题的非常非常好的文章。
此外，我的 Maven POM 文件中有：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<!--<packagingExcludes>WEB-INF/web.xml</packagingExcludes>-->
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
更新
您的 Spring 配置工作正常（但您确实可以进一步改进它）；当您呼叫 HibernateConfig.InitialiseDummyData(); 时，问题出在 LoginController 线上。评论那一行，一切都会好起来的。
调用该方法时，您正在启动另一个 Spring 上下文。我无法修复数据库的问题，因为我没有您的架构...在进行 概念验证 时最好使用内存数据库。尝试 improve/fix 那段代码，你应该可以开始了。
