Question

我在JSP页面中有错误。错误是文本变量具有geters和setter方法，但模型具有这些方法

这是我的模特：

@Entity
public class Comentario implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@Column(columnDefinition="TEXT")    
@Size(min = 5, message = "Mínimo 5 caracteres")
private String texto;

@DateTimeFormat(pattern = "dd/mm/yyyy")
private Date data;

@ManyToOne
@JoinColumn(name = "usuario_id")
@JsonBackReference
private Usuario usuario;

@ManyToOne
@JoinColumn(name = "projeto_id")
@JsonBackReference
private Projeto projeto;

public Comentario() {
    super();
}

public Comentario(Long id, String texto, Date data, Usuario usuario,
        Projeto projeto) {
    super();
    this.id = id;
    this.texto = texto;
    this.data = data;
    this.usuario = usuario;
    this.projeto = projeto;
}

public Long getId() {
    return id;
}

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

public String getTexto() {
    return texto;
}

public void setTexto(String texto) {
    this.texto = texto;
}

public Date getData() {
    return data;
}

public void setData(Date data) {
    this.data = data;
}

public Usuario getUsuario() {
    return usuario;
}

public void setUsuario(Usuario usuario) {
    this.usuario = usuario;
}

public Projeto getProjeto() {
    return projeto;
}

public void setProjeto(Projeto projeto) {
    this.projeto = projeto;
}
}

在我的jsp页面中有代码：

当我访问该页面时显示错误：

org.springframework.beans.NotReadablePropertyException: Invalid property 'texto' of bean class [java.util.ArrayList]: Bean property 'texto' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
