Java hbm2ddl模式导出不'；不会导致使用Spring安全性创建实体

我使用Spring入门内容。 我通常可以在访问mysql数据的项目中创建实体，而不能在安全web complete中创建任何实体。 我创建了相同的依赖项，并在访问mysql数据的项目中添加了

application.properties

文件

application.properties

文件

spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/sportfacilitydb
spring.datasource.username=root
spring.datasource.password=root
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.cache=false

package User;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity // This tells Hibernate to make a table out of this class
public class User {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;

    private String name;

    private String email;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }


}

但什么也没发生，所以我把这归咎于spring security

运行应用程序后，在控制台上，我可以注意到以下行：

2017-01-29 12:19:05.511  INFO 9532 --- [  restartedMain] j.LocalContainerEntityManagerFactoryBean : Building JPA container EntityManagerFactory for persistence unit 'default'

所以它说模式被创建并导出？但为什么我不能在数据库中看到它呢？ 我尝试创建的实体类：

User.java

文件

spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/sportfacilitydb
spring.datasource.username=root
spring.datasource.password=root
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.cache=false

package User;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity // This tells Hibernate to make a table out of this class
public class User {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;

    private String name;

    private String email;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }


}

这是我的

SpringSecurity

配置文件：

WebSecurityConfig.java

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/index", "/register", "/aboutus", "/contactus", "/css/**", "/images/**", "/bootstrap/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .defaultSuccessUrl("/index")
                .and()
            .logout()
                .permitAll()
                .logoutSuccessUrl("/index");


    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER");
    }
}

和

Application.java

文件：

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Throwable {
        SpringApplication.run(Application.class, args);
    }

}

更新 实际上这是我的致命错误。根据Spring boot文档：

默认情况下，主配置类（ 用@EnableAutoConfiguration或@springbootplication注释） 将进行搜索

---

因此，我有第二个名为“User”的并行包，SpringBootApplication配置找不到它。

我想您忘了在

应用程序中添加此属性。属性

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

别忘了将以下内容添加到pom.xml中：

<dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
 <version>${version}</version>
</dependency>


mysql
mysql连接器java
${version}
spring.datasource.driver class name=“com.mysql.jdbc.driver”
属性在spring入门内容中的正常工作项目中不存在，将其添加到application.properties会产生一些错误。还刚刚从我的项目中添加了整个pom.xml。应该没有双引号。。并添加mysql连接器的显式版本和编译范围。。如果属性不足，请将更新作为答案发布？谢谢
