英文:
Spring: can't access controller 404 not found error
问题
我正尝试访问 http://localhost:8088/test_war_exploded/home/hello，但是出现了 404 错误。我无法弄清楚为什么会出现这个错误。
目录结构:
root
src
main
java
test
config
DbConfig.java
MyAppInitializer.java
WebConfig.java
HomeController.java
WebConfig.java:
@Configuration
@ComponentScan("test")
@EnableWebMvc
@EnableTransactionManagement
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableJpaRepositories(basePackages = "test",
entityManagerFactoryRef = "entityManagerFactory",
transactionManagerRef = "transactionManager")
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void configureDefaultServletHandling(
DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
}
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver bean = new InternalResourceViewResolver();
bean.setViewClass(JstlView.class);
bean.setPrefix("/WEB-INF/view/");
bean.setSuffix(".html");
return bean;
}
}
MyAppInitializer.java:
public class MyAppInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
@Override
public void onStartup(final ServletContext sc) throws ServletException {
System.out.println("onStartup!");
AnnotationConfigWebApplicationContext root =
new AnnotationConfigWebApplicationContext();
root.register(WebConfig.class);
root.setServletContext(sc);
root.scan("test");
//sc.addListener(new ContextLoaderListener(root));
ServletRegistration.Dynamic appServlet =
sc.addServlet("dispatcher", new DispatcherServlet(new GenericWebApplicationContext()));
appServlet.setLoadOnStartup(1);
appServlet.addMapping("/");
}
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {SecurityConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{WebConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
HomeController.java:
@RestController
@RequestMapping("/home")
public class HomeController {
@GetMapping(value = "/hello")
public String hello() {
return "Hello";
}
}
该应用在服务器/IDE日志中没有错误进行部署。在部署过程中，在控制台中会打印出 onStartup，这意味着 MyAppInitializer 中的代码被执行。

}
HomeController.java:
@RestController
@RequestMapping("/home")
public class HomeController {
@GetMapping(value = "/hello")
public String hello() {
return "Hello";
}
}
The app gets deployed with no errors in server / IDE log. During deployment onStartup gets printed in console, meaning the code in MyAppInitializer gets executed.

得分: 1
HomeController为/home提供了映射。
要访问上述端点，您可以将第一部分添加到RequestMapping注释中，如下所示：@RequestMapping("test_war_exploded/home")
并且您尝试通过端口8088进行访问。默认端口为8080，除非在application.properties中进行了设置。
英文:
The HomeController provides a mapping for /home.
For accessing the mentioned endpoint you could add the first part to the RequestMapping Annotation as such: @RequestMapping("test_war_exploded/home")
And you try to access via port 8088. The default port is 8080, if not set in the application.properties otherwise.

得分: -1
HomeController bean未定义且未初始化。
@Component
@RestController
@RequestMapping("/home")
public class HomeController {
@GetMapping(value = "/hello")
public String hello() {
return "你好";
}
}
英文:
HomeController bean is not defined and not initialized.
@Component
@RestController
@RequestMapping("/home")
public class HomeController {
@GetMapping(value = "/hello")
public String hello() {
return "Hello";
}
}

我解决了。问题是我没有初始化类。我添加了两个类：SecurityConfig 和 SecurityWebApplicationInitializer：
SecurityConfig.java：
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled=true)
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().antMatchers("/").permitAll();
}
@Bean
BCryptPasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
SecurityWebApplicationInitializer.java：
public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
public SecurityWebApplicationInitializer() {
super(SecurityConfig.class, WebConfig.class);
}
}
现在我的项目看起来是这样的：
Main.java 仅用于 maven-shade-plugin，不用在意它，它只包含一个空的 main 方法：
Main.java：
public class Main {
public static void main(String[] args) {
}
}
我的其他类（已更新）。出于简化考虑，我移除了数据库配置类。如果你不需要数据库，只需从这个回答中复制粘贴类，应该可以正常工作：
MyAppInitializer.java：
public class MyAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
public void onStartup(final ServletContext sc) throws ServletException {
System.out.println("onStartup!");
AnnotationConfigWebApplicationContext root = new AnnotationConfigWebApplicationContext();
root.register(WebConfig.class);
root.setServletContext(sc);
root.scan("test");
//sc.addListener(new ContextLoaderListener(root));
ServletRegistration.Dynamic appServlet =
sc.addServlet("dispatcher", new DispatcherServlet(new GenericWebApplicationContext()));
appServlet.setLoadOnStartup(1);
appServlet.addMapping("/");
}
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {SecurityConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{WebConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
WebConfig.java：
@Configuration
@ComponentScan("test")
@EnableWebMvc
@EnableTransactionManagement
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableJpaRepositories(basePackages = "test",
entityManagerFactoryRef = "entityManagerFactory", transactionManagerRef = "transactionManager")
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
HomeController.java：
@RestController
public class HomeController {
@GetMapping("/")
public String getHome() {
return "home";
}
}
TestController.java：
@RestController
public class TestController {
@RequestMapping("/test")
public String test() {
return "test";
}
}
我从配置类中移除了视图解析器，因为我只打算使用 rest controller 作为 API 提供者。感谢收听我的 TED 演讲。
PS 这是我的 pom.xml 如何配置的（因为使用不同的 poms，Intellij 不会自动生成 war-exploded 构件）：
（你的 pom.xml 部分被截断，我无法提供完整的翻译。）
英文:
I figured it out. The problem was that I didn't have an initializer class. I added two classes: SecurityConfig and SecurityWebApplicationInitializer:
SecurityConfig.java:
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled=true)
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().antMatchers("/").permitAll();
}
@Bean
BCryptPasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
SecurityWebApplicationInitializer.java:
public class SecurityWebApplicationInitializer extends
AbstractSecurityWebApplicationInitializer {
public SecurityWebApplicationInitializer() {
super(SecurityConfig.class, WebConfig.class);
}
}
This is how my project looks now:
Main.java is just for the maven-shade-plugin, never mind it, it only contains the empty main method:
Main.java:
public class Main {
public static void main(String[] args) {
}
}
My other classes (updated). I removed database config class for simplicity. If you don't need a database, you can just copypaste classes from this answer and it should work fine:
MyAppInitializer.java:
public class MyAppInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
@Override
public void onStartup(final ServletContext sc) throws ServletException {
System.out.println("onStartup!");
AnnotationConfigWebApplicationContext root =
new AnnotationConfigWebApplicationContext();
root.register(WebConfig.class);
root.setServletContext(sc);
root.scan("test");
//sc.addListener(new ContextLoaderListener(root));
ServletRegistration.Dynamic appServlet =
sc.addServlet("dispatcher", new DispatcherServlet(new GenericWebApplicationContext()));
appServlet.setLoadOnStartup(1);
appServlet.addMapping("/");
}
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {SecurityConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{WebConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
WebConfig.java:
@Configuration
@ComponentScan("test")
@EnableWebMvc
@EnableTransactionManagement
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableJpaRepositories(basePackages = "test",
entityManagerFactoryRef = "entityManagerFactory", transactionManagerRef = "transactionManager")
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
@Override
public void configureDefaultServletHandling(
DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
HomeController.java:
@RestController
public class HomeController {
@GetMapping("/")
public String getHome() {
return "home";
}
}
TestController.java:
@RestController
public class TestController {
@RequestMapping("/test")
public String test() {
return "test";
}
}
I removed view resolvers from config classes, because I intend to only use rest controllers as an API provider. Thanks for coming to my TED talk.

}
}
