我正在创建一个 Spring Boot 应用程序。当我运行应用程序时，数据库表没有创建。
这是我的application.properties 文件
spring.datasource.url=jdbc:mysql://localhost/aymuws
spring.datasource.username=root
spring.datasource.password=1101289217
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
User 存储库类
package com.technostack.aymuws.entities;
@Entity
@Table(name="user")
public class User {
@Id
@Email
@NotEmpty
@Column(unique=true)
private String email;
@Column(name="_name",unique=false,nullable=false,length=100)
@NotEmpty
private String name;
@Column(name="_password",unique=true,nullable=false)
@NotEmpty
@Size(max=12,min=6)
private String password;
@Column(name="_task")
@OneToMany(mappedBy="user",cascade=CascadeType.ALL)
private List<Task> tasks;
@Column(name="_roles")
@ManyToMany(cascade=CascadeType.ALL)
@JoinTable(name="USER_ROLES",joinColumns= {
@JoinColumn(name="USER_EMAIL",referencedColumnName="email")
},inverseJoinColumns= {
@JoinColumn(name="ROLE_NAME",referencedColumnName="name")
})
private List<Roles> roles;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public List<Task> getTasks() {
return tasks;
}
public void setTasks(List<Task> tasks) {
this.tasks = tasks;
}
public List<Roles> getRoles() {
return roles;
}
public void setRoles(List<Roles> roles) {
this.roles = roles;
}
public User(String email, String name, String password) {
this.email = email;
this.name = name;
this.password = password;
}
public User() {
}
}
Task 存储库类
package com.technostack.aymuws.entities;
@Entity
public class Task {
@Id
@GeneratedValue
private Long task_id;
@NotEmpty
private String date;
@NotEmpty
private String starttime;
@NotEmpty
private String stoptime;
@NotEmpty
private String description;
@ManyToOne
@JoinColumn(name="USER_EMAIL",referencedColumnName="email")
private User user;
// Constructors, setters & getters
}
以及Role存储库类
package com.technostack.aymuws.entities;
@Entity
public class Roles {
@Id
private String name;
@ManyToMany(mappedBy="roles")
private List<User> users;
// Constructor, getters and setters
}
服务类如下。
package com.technostack.aymuws.service;
@Service
public class UserService {
@Autowired
private UserRepository userRepository;
public void createUser(User user) {
BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
user.setPassword(encoder.encode(user.getPassword()));
Roles user_role = new Roles("USER");
List<Roles> create_role = new ArrayList<>();
create_role.add(user_role);
user.setRoles(create_role);
userRepository.save(user);
}
public void createAdmin(User user) {
BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
user.setPassword(encoder.encode(user.getPassword()));
Roles user_role = new Roles("ADMIN");
List<Roles> create_role = new ArrayList<>();
create_role.add(user_role);
user.setRoles(create_role);
userRepository.save(user);
}
public User findone(String email) {
return userRepository.findOne(email);
}
}
这是我运行应用程序时的控制台。

我正在属性文件中配置所有数据库信息。但是，执行应用程序后，我无法创建数据库。
最佳答案
在 application.properties 中更改此配置并查看其是否正常工作
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/aymuws?autoReconnect=true&verifyServerCertificate=false&useSSL=false&requireSSL=false
关于java - 在 Spring Boot 中 - 应用程序数据库未创建，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55786273/
