我正在开发一个带有spring boot和spring security以及jwt的应用程序，但是当我运行我的应用程序时，我遇到了以下无法解决的错误：
java.lang.illegalstateexception:未能在org.springframework.boot.springapplication.callrunner（springapplication）上执行commandlinerunner。java:807)[Spring Boot-2.4.1。jar:2.4.1]在org.springframework.boot.springapplication.callrunners（springapplication。java:788)[Spring Boot-2.4.1。jar:2.4.1]在org.springframework.boot.springapplication.run（springapplication。java:333)[Spring Boot-2.4.1。jar:2.4.1]在org.springframework.boot.springapplication.run（springapplication。java:1309)[Spring Boot-2.4.1。jar:2.4.1]在org.springframework.boot.springapplication.run（springapplication。java:1298)[Spring Boot-2.4.1。jar:2.4.1]在courtjwtudemy.jwtproject.jwtprojectapplication.main（jwtprojectapplication。java:30)[classes/：na]位于sun.reflect.nativemethodaccessorimpl.invoke0（本机方法）~[na:1.8.0111]位于sun.reflect.nativemethodaccessorimpl.invoke（nativemethodaccessorimpl）。java:62)~（na:1.8.0μ111）在sun.reflect.delegatingmethodaccessorimpl.invoke（delegatingmethodaccessorimpl。java:43)~[na:1.8.0\u 111]位于java.lang.reflect.method.invoke（method。java:498)~[na:1.8.0\u111]位于org.springframework.boot.devtools.restart.restartlauncher.run（restartlauncher。java:49)[spring-boot-devtools-2.4.1。jar:2.4.1]
这是我的主要 Spring 靴类：

package courtjwtudemy.jwtproject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import courtjwtudemy.jwtproject.dao.MyUserReporisitory;
import courtjwtudemy.jwtproject.dao.ProductReporisitory;
import courtjwtudemy.jwtproject.entity.MyRole;
import courtjwtudemy.jwtproject.entity.Product;
import courtjwtudemy.jwtproject.service.AccountService;
@SpringBootApplication
public class JwtProjectApplication implements CommandLineRunner{
    @Autowired
    private ProductReporisitory prodRepository;
    @Autowired
    private MyUserReporisitory myUserReporisitory;
    @Autowired
    private AccountService accountService;
    public static void main(String[] args) {
        SpringApplication.run(JwtProjectApplication.class, args);
    }
    @Bean
    BCryptPasswordEncoder getBCPE() {
        return new BCryptPasswordEncoder();
    }
    @Override
    public void run(String... args) throws Exception {
        // TODO Auto-generated method stub
        Product p = new Product();
        p.setName("chargeur de soleil");
        p.setDescription("hazar");
        p.setPrice(45);
        p.setPhoto("https://cdn3.lingerie-sipp.com/36357-large_default/debardeur-homme-isolant-innovation-20-noir.jpg");
        p.setPromotion(false);
        prodRepository.save(p);
        // add user
        accountService.saveRole(new MyRole(null, "User"));
        accountService.saveRole(new MyRole(null, "Admin"));
        accountService.saveUser("nawfal", "bgr", "bgr");
        accountService.saveUser("admin", "bgr", "bgr");
        accountService.saveUser("user", "bgr", "bgr"); 
        myUserReporisitory.findAll().forEach(u -> {
            System.out.println("user :" + u.getUsername() + "password :" + u.getPassword());
        });
    }
}

下面是我的实体用户类：

package courtjwtudemy.jwtproject.entity;
import java.util.ArrayList;
import java.util.Collection;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToMany;
import com.fasterxml.jackson.annotation.JsonProperty;
@Entity
public class MyUser {
    @Id
    @GeneratedValue (strategy = GenerationType.IDENTITY)
    private Long id;
    @Column(unique = true)
    private String username;
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private String password;
    @ManyToMany(fetch = FetchType.EAGER)
    private Collection<MyRole> roles = new ArrayList<>();
    public MyUser() {
        super();
    }
    public MyUser(Long id, String username, String password, Collection<MyRole> roles) {
        super();
        this.id = id;
        this.username = username;
        this.password = password;
        this.roles = roles;
    }
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public Collection<MyRole> getRoles() {
        return roles;
    }
    public void setRoles(Collection<MyRole> roles) {
        this.roles = roles;
    }
}

下面是我的实体角色类：

package courtjwtudemy.jwtproject.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class MyRole {
    @Id
    @GeneratedValue (strategy = GenerationType.IDENTITY)
    private Long id;
    private String roleName;
    public MyRole(Long id, String roleName) {
        super();
        this.id = id;
        this.roleName = roleName;
    }
    public MyRole() {
        super();
    }
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getRoleName() {
        return roleName;
    }
    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }
}

有人能帮我吗？
