每个人!打扰一下,我是 Spring 技术的初学者。我正在使用 SpringMVC,我无法通过我的 RestController 方法获取任何 HTML 页面,但我成功获取了 JSON 或字符串对象中的对象。任何帮助,当我想获取 HTML 页面时,为什么我会在 Catalina 日志中永久收到此消息?
org.springframework.web.servlet.DispatcherServlet.noHandlerFound No mapping for GET /WEB-INF/pages/login.html
相应的 HTML 文件存在,但 mb HandlerMapping 没有找到它们。当我访问 URL 时,我必须添加到我的项目中以在我的浏览器中获取我的 HTML 页面http://localhost:8080/login
?
我使用 Java 配置而不是 XML 文件。我的整个项目位于 GitHub https://github.com/OlegSandro/first-rest-project/tree/security
:. 一些主要细节如下所示。
我的控制器:
package com.example.controller;
import com.example.model.User;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.ModelAndView;
import java.util.concurrent.atomic.AtomicLong;
@RestController
public class TestController {
@GetMapping("/profile")
public String profile() {
return "profile";
}
@GetMapping("/home")
public String home() {
return "/home";
}
@GetMapping("/login")
public ModelAndView login() {
User user = new User();
user.setLogin("superuser");
user.setPassword("124567890");
user.setId_role(2);
return new ModelAndView("login", "login", user);
//return new ModelAndView("login");
}
}
我的第一个配置类:
package com.example.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.example.controller" })
//@ComponentScan(basePackages = "com.example")
public class WebConfiguration extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver()
{
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/pages/");
viewResolver.setSuffix(".html");
return viewResolver;
}
}
我的第二个配置类:
package com.example.configuration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {AppConfiguraion.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] {WebConfiguration.class};
}
@Override
protected String[] getServletMappings() {
return new String[] {"/"};
}
}
我的第三个配置类(用于 Hibernate 功能,因为 ORM 是我项目的另一部分):
package com.example.configuration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.*;
import org.springframework.core.env.Environment;
import org.springframework.orm.hibernate5.*;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import static org.hibernate.cfg.AvailableSettings.*;
import java.util.Properties;
@Configuration
@PropertySource("classpath:db.properties")
@EnableTransactionManagement
@ComponentScans(value = { @ComponentScan("com.example.dao"), @ComponentScan("com.example.service")})
public class AppConfiguraion {
@Autowired
private Environment env;
@Bean
public LocalSessionFactoryBean getSessionFactory(){
LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();
Properties props = new Properties();
// Setting JDBC properties
props.put(DRIVER, env.getProperty("mysql.driver"));
props.put(URL, env.getProperty("mysql.url"));
props.put(USER, env.getProperty("mysql.user"));
props.put(PASS, env.getProperty("mysql.password"));
// Setting Hibernate properties
props.put(SHOW_SQL, env.getProperty("hibernate.show_sql"));
props.put(HBM2DDL_AUTO, env.getProperty("hibernate.hbm2ddl.auto"));
// Setting C3P0 properties
props.put(C3P0_MIN_SIZE, env.getProperty("hibernate.c3p0.min_size"));
props.put(C3P0_MAX_SIZE, env.getProperty("hibernate.c3p0.max_size"));
props.put(C3P0_ACQUIRE_INCREMENT, env.getProperty("hibernate.c3p0.acquire_increment"));
props.put(C3P0_TIMEOUT, env.getProperty("hibernate.c3p0.timeout"));
props.put(C3P0_MAX_STATEMENTS, env.getProperty("hibernate.c3p0.max_statements"));
factoryBean.setHibernateProperties(props);
factoryBean.setPackagesToScan("com.example.model");
return factoryBean;
}
@Bean
public HibernateTransactionManager getTransactionManager(){
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(getSessionFactory().getObject());
return transactionManager;
}
}
感谢您提前提供任何帮助!
