引起以下问题的主要原因就是jackson把懒加载也作为pojo进行序列化了。

json序列化报错:

在orm的实体中加入以下代码

@JsonIgnore

    @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH},fetch = FetchType.LAZY)

    @JoinColumn(name = "first_user")

    public User getFirstUser() {

        return firstUser;

    }

    @JsonManagedReference

    public void setFirstUser(User firstUser) {

        this.firstUser = firstUser;

    }
