Well, I have a problem that has never occurred to me before regarding Spring MVC binding.

I have a form as below. The bindind "firstName" and "lastName" tags work fine, but the "logins.email"

<f:form class="form-signin" method="post" action="addAgency" modelAttribute="tenant">

    <div class="input-group">
        <span class="input-group-addon entypo-user"></span>
        <f:input path="firstName" type="text" class="form-control"
            placeholder="Nome" />
    </div>

    <br>

    <div class="input-group">
        <span class="input-group-addon entypo-user"></span>
        <f:input path="lastName" type="text" class="form-control"
            placeholder="Sobrenome" />
    </div>

    <br>

    <div class="input-group">
        <span class="input-group-addon entypo-mail"></span>
        <f:input path="logins.email" type="text" class="form-control"
            placeholder="E-mail" />logins
    </div>

        <!-- Restante de Formulário -->

The following stackTrace is displayed:

Well, the problem is that I have their getters and setters in my project. Below are the reduced form templates:

Agencia.java

@Entity
@Table(name="agency")
@NamedQuery(name="Agency.findAll", query="SELECT a FROM Agency a")
public class Agency implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id_agency")
    private Long idAgency;

    @Column(name="first_name")
    private String firstName;

    @Column(name="last_name")
    private String lastName;

    @Column(name="subdomain")
    private String subdomain;

    //bi-directional many-to-one association to Login
    @OneToMany(mappedBy="agency")
    private Set<Login> logins;

    public Agency() {
    }

    public Long getIdLogin(){
        return idAgency;
    }

    public void setIdLogin(Long idLogin) {
        this.idAgency = idLogin;
    }

    public String getFirstName() {
        return this.firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return this.lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getSubdomain() {
        return this.subdomain;
    }

    public void setSubdomain(String subdomain) {
        this.subdomain = subdomain;
    }

    public Set<Login> getLogins() {
        return logins;
    }

    public void setLogins(Set<Login> logins) {
        this.logins = logins;
    }

    @Override
    public String toString() {
        return "ID=" + idAgency + ", Sub-Dominio=" + subdomain;
    }

}

Login.java

@Entity
@Table(name="login")

    private Long idLogin;

    @Column(name="email")
    private String email;

    @Column(name="master")
    private Boolean master;

    @Column(name="password")
    private String password;

    //bi-directional many-to-one association to Agency
    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name="fk_agency")
    private Agency agency;

    @Enumerated(EnumType.STRING)
    @Column(name="user_role")
    private Role role;

    @Column(name="tenant_id", insertable=false, updatable=false)
    private Long tenantId;

    public Login() {
    }

    public Long getIdLogin() {
        return this.idLogin;
    }

    public void setIdLogin(Long idLogin) {
        this.idLogin = idLogin;
    }

    public String getEmail() {
        return this.email;
    }

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

    public Boolean getMaster() {
        return this.master;
    }

    public void setMaster(Boolean master) {
        this.master = master;
    }

    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Agency getAgency() {
        return this.agency;
    }

    public void setAgency(Agency agency) {
        this.agency = agency;
    }

    public Long getTenantId() {
        return tenantId;
    }

    public Role getRole() {
        return role;
    }

    public void setRole(Role role) {
        this.role = role;
    }

}

Separate result in different worksheets What is the difference between these expressions?

Spring MVC will not bind binding from a field to a set.

However, if the idea is to receive a comma separated list of emails, just to give an example, a simple solution would be to create a setter that receives a String and uses split to break into multiple items by adding them to the set.

In addition, the corresponding getter would join the elements of the set, separating them by commas, and return the result in a single String .
