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。
解决方法：在该实体类的所有关联集合类上加上
@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})就OK了
比如:
package com.hzboy.orm; import java.util.Date; import javax.persistence.CascadeType; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.JoinColumn; import javax.persistence.ManyToOne; import javax.persistence.OneToOne; import javax.persistence.Table; import javax.persistence.Transient; import org.codehaus.jackson.annotate.JsonIgnore; import org.codehaus.jackson.annotate.JsonIgnoreProperties; import org.codehaus.jackson.annotate.JsonManagedReference; /** * * @author xiefeng * */ @Entity @Table(name = "t_computer") public class Computer extends BaseEntity { // 电脑类型 private String computerType; // 电脑型号 private String computerName; // cpu信息 private String cpuInfo; // 内存信息 private String ramInfo; // 硬盘大小 private String storge; // 显卡类型 private String diaplayType; // 主机编码 private String hostID; // 显示器型号 private String displayID; // 备注 private String remark; // 出厂日期 private Date time; // 当前使用人 private User currentUser; // 使用人id private Integer userId; // 领用日期 private Date startDate; // 所属部门 private Department department; // 部门id private Integer departmentId; //用途 private String purpose; //使用人姓名 private String userName; public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPurpose() { return purpose; } public void setPurpose(String purpose) { this.purpose = purpose; } @Column(name = "computer_type") public String getComputerType() { return computerType; } public void setComputerType(String computerType) { this.computerType = computerType; } @Column(name = "computer_name") public String getComputerName() { return computerName; } public void setComputerName(String computerName) { this.computerName = computerName; } @Column(name = "cpu_info") public String getCpuInfo() { return cpuInfo; } public void setCpuInfo(String cpuInfo) { this.cpuInfo = cpuInfo; } @Column(name = "ram_info") public String getRamInfo() { return ramInfo; } public void setRamInfo(String ramInfo) { this.ramInfo = ramInfo; } public String getStorge() { return storge; } public void setStorge(String storge) { this.storge = storge; } @Column(name = "diaplay_type") public String getDiaplayType() { return diaplayType; } public void setDiaplayType(String diaplayType) { this.diaplayType = diaplayType; } @Column(name = "host_id") public String getHostID() { return hostID; } public void setHostID(String hostID) { this.hostID = hostID; } @Column(name = "display_id") public String getDisplayID() { return displayID; } public void setDisplayID(String displayID) { this.displayID = displayID; } public String getRemark() { return remark; } public void setRemark(String remark) { this.remark = remark; } @Column(columnDefinition = "date") public Date getTime() { return time; } public void setTime(Date time) { this.time = time; } @ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }, fetch = FetchType.LAZY) @JoinColumn(name = "current_user_id") public User getCurrentUser() { return currentUser; } @JsonManagedReference public void setCurrentUser(User currentUser) { this.currentUser = currentUser; } @Transient public Integer getUserId() { return userId; } public void setUserId(Integer userId) { this.userId = userId; } @Column(name="start_date",columnDefinition = "date") public Date getStartDate() { return startDate; } public void setStartDate(Date startDate) { this.startDate = startDate; } @ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE }, fetch = FetchType.LAZY) @JoinColumn(name = "dept_id") public Department getDepartment() { return department; } @JsonManagedReference public void setDepartment(Department department) { this.department = department; } @Transient public Integer getDepartmentId() { return departmentId; } public void setDepartmentId(Integer departmentId) { this.departmentId = departmentId; } }
比如以上实体中引用了2个类:User 和 Department,那么这2个类必须加上
@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
如下:
