現在、Spring MVC + Hibernate + Maven Web アプリケーションをセットアップしています。

Tomcat を使用したアプリケーションの実行を禁止する JUnit エラーのある Im スタック

JUnit の障害トレースは次のとおりです。

テストのために、私は2つのクラスを持っています。最初のものは: BaseTestConfig.java :

@Configuration
@ComponentScan("com.mycompany.webAppDemo")
@EnableWebMvc
public class BaseTestConfig {

    @Bean
    public UrlBasedViewResolver setupViewResolver() {
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/WEB-INF/pages/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

}

2 つ目は LinkControllerClasses.java です。

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes=BaseTestConfig.class)
public class LinkControllerTest {

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void init() {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @Test
    public void testHomePage() throws Exception {
        mockMvc.perform(get("/"))
            .andExpect(status().isOk())
            .andExpect(view().name("home"));
    }

    @Test
    public void testIndexPage() throws Exception {
        mockMvc.perform(get("/index.html"))
            .andExpect(status().isOk())
            .andExpect(view().name("home"));
    }

}

私のアプリケーション構成には、2 つのクラスがあります: Initializer.java

public class Initializer implements WebApplicationInitializer{

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        // TODO Auto-generated method stub
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(WebAppConfig.class);
        servletContext.addListener(new ContextLoaderListener(ctx));

        ctx.setServletContext(servletContext);

        Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);
    }
}

そして WebAppConfig.java :

@Configuration
@ComponentScan("com.mycompany.webAppDemo")
@EnableWebMvc
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
public class WebAppConfig {

    private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
    private static final String PROPERTY_NAME_DATABASE_PASSWORD = "";
    private static final String PROPERTY_NAME_DATABASE_URL = "jdbc:mysql://127.0.0.1:3306/demodb";
    private static final String PROPERTY_NAME_DATABASE_USERNAME = "root";

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "org.hibernate.dialect.MySQL5InnoDBDialect";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "true";
    private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "com.amadeus.webAppDemo.model";

    @Resource
    private Environment env;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
        dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
        dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
        dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));

        return dataSource;
    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource());
        sessionFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
        sessionFactoryBean.setHibernateProperties(hibProperties());
        return sessionFactoryBean;
    }

    private Properties hibProperties() {
        Properties properties = new Properties();
        properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
        properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
        return properties;  
    }

    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());
        return transactionManager;
    }

    @Bean
    public UrlBasedViewResolver setupViewResolver() {
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/WEB-INF/pages/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

}

最後に、2 つのコントローラー クラスを次に示します。

LinkControl.java

@Controller
public class LinkController {

     @RequestMapping(value="/")  
        public ModelAndView mainPage() {  
            return new ModelAndView("home");  
        }  

     @RequestMapping(value="/index")  
        public ModelAndView indexPage() {  
            return new ModelAndView("home");  
        } 

}

TeamController.java

@Controller
public class TeamController {

    @Autowired
    private TeamService teamService; 

    @RequestMapping(value="/team/add")
    public ModelAndView addTeamPage(){
        ModelAndView modelAndView = new ModelAndView("add-team-form");
        modelAndView.addObject("team", new Team());
        return modelAndView;
    }

    @RequestMapping(value="/team/add/process")
    public ModelAndView addingTeam(@ModelAttribute Team team){
        ModelAndView modelAndView = new ModelAndView("home");
        teamService.addTeam(team);

        String message ="Team was successfully added";
        modelAndView.addObject("message", message); 

        return modelAndView;  
    }

    @RequestMapping(value="/team/list")  
    public ModelAndView listOfTeams() {  
        ModelAndView modelAndView = new ModelAndView("list-of-teams");  

        List<Team> teams = teamService.getTeams();  
        modelAndView.addObject("teams", teams);  

        return modelAndView;  
    }

      @RequestMapping(value="/team/edit/{id}", method=RequestMethod.GET)  
        public ModelAndView editTeamPage(@PathVariable Integer id) {  
            ModelAndView modelAndView = new ModelAndView("edit-team-form");  
            Team team = teamService.getTeam(id);  
            modelAndView.addObject("team",team);  
            return modelAndView;  
        }  

      @RequestMapping(value="/team/edit/{id}", method=RequestMethod.POST)  
        public ModelAndView edditingTeam(@ModelAttribute Team team, @PathVariable Integer id) {  

            ModelAndView modelAndView = new ModelAndView("home");  

            teamService.updateTeam(team);  

            String message = "Team was successfully edited.";  
            modelAndView.addObject("message", message);  

            return modelAndView;  
        }  

      @RequestMapping(value="/team/delete/{id}", method=RequestMethod.GET)  
        public ModelAndView deleteTeam(@PathVariable Integer id) {  
            ModelAndView modelAndView = new ModelAndView("home");  
            teamService.deleteTeam(id);  
            String message = "Team was successfully deleted.";  
            modelAndView.addObject("message", message);  
            return modelAndView;  
        }  
}

同様の問題の提案された修正を試みました Failed to load ApplicationContext with @ContextConfiguration(classes={ ... })

しかし、それは機能していません:(

ご回答ありがとうございます。ここに application.properties があります

#DB properties:
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/demodb
db.username=root
db.password=*****

#Hibernate Configuration:
hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.show_sql=true
entitymanager.packages.to.scan=com.mycompany.webAppDemo.model

私は私の WebAppConfig.java.For eg.inside にいくつかの変更を加えました:

private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";

私はこれをします ：

private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";

しかし、まだ同じエラーがあります:(

Spring の Environment クラスのgetRequiredProperty()メソッドは、プロパティを解決できない場合、IllegalStateException をスローします。あなたはこれをしようとしています：

dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));

キーでプロパティを取得しようとします

private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";

プロパティファイルに次のエントリがない限り、意味がありません。

com.mysql.jdbc.Driver=com.mysql.jdbc.Driver

あなたが望むのは次のいずれかだと思います：

private static final String PROPERTY_NAME_DATABASE_DRIVER = "driverClassName";
// in properties file
...
driverClassName=com.mysql.jdbc.Driver
...

また

dataSource.setDriverClassName(PROPERTY_NAME_DATABASE_DRIVER);

プロパティファイルではなく直接設定します。

application.properties詳細が必要な場合は、ファイルの内容を投稿してください。
