私は基本的なSpringBootアプリケーションを持っています。実行可能JARファイルとして春初期化子、組み込みのTomcat、Thymeleafのテンプレートエンジン、およびパッケージを使用してThymeleafテンプレートのPOJOオブジェクト
私は、このドメインのオブジェクトがあります。
@Entity
@Table(name="t_user")
public class User implements Serializable, UserDetails {
@OneToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Company company;
public Company getCompany() {
return company;
}
public void setCompany(Company company) {
this.company = company;
}
..
}
と
@Entity
@Table(name="t_company")
public class Company implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
public Company() {
}
/**
* @param companyName
*/
public Company(String companyName) {
super();
this.name = companyName;
}
@NotEmpty
@Length(max = 100)
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "Company [id=" + id + ", name=" + name + ", timeLapses=" + timeLapses + ", applications=" + applications
+ "]";
}
..
}
しかしを、私はの値を取得するときThymeleafテンプレートの会社名：
<td class="col_company" th:text="${user.company.name}"></td><!-- COMPANY NAME -->
このエラーが発生しました：
