錯誤代碼

@OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER, mappedBy="user")
    public Set getEnvelopeReceivers() {
        return this.envelopeReceivers;

    }

    public void setEnvelopeHistories(Set<EnvelopeHistory> envelopeHistories) {

    }

正確的代碼

 public Set<EnvelopeReceiver> getEnvelopeReceivers() {
        return envelopeReceivers;
    }

    public void setEnvelopeReceivers(Set<EnvelopeReceiver> envelopeReceivers) {
        this.envelopeReceivers = envelopeReceivers;
    }
    @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER, mappedBy="user")

    public Set<Envelope> getEnvelopes() {
        return envelopes;
    }

    public void setEnvelopes(Set<Envelope> envelopes) {
        this.envelopes = envelopes;
    }
    @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER, mappedBy="user")
    public Set<EnvelopeHistory> getEnvelopeHistories() {
        return envelopeHistories;
    }

    public void setEnvelopeHistories(Set<EnvelopeHistory> envelopeHistories) {
        this.envelopeHistories = envelopeHistories;
    }

set 的地方沒有加 泛型！！！！
