Spring Boot启动报错MojoExecutionException排查与解决

错误信息

运行Spring Boot应用时触发org.apache.maven.plugin.MojoExecutionException，具体日志如下：

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:3.0.2:run (default-cli) on project demo: Process terminated with exit code: 1 -> [Help 1]

相关实体类代码

Student.java 

package com.example.demo.entity;

import java.time.LocalDate;
import java.util.HashSet;
import java.util.Set;

import com.fasterxml.jackson.annotation.JsonIgnore;

import jakarta.persistence.Entity;
import jakarta.persistence.Table;
import jakarta.persistence.JoinColumn;
import jakarta.persistence.JoinTable;
import jakarta.persistence.ManyToMany;

import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
import lombok.ToString;

@Entity
@Table(name = "Student")
@ToString
@NoArgsConstructor
public class Student extends User {

    public Student(String name, String email, LocalDate dob) {
        setName(name);
        setEmail(email);
        setDob(dob);
    }

    @ManyToMany
    @JoinTable(
        name = "enrolled", 
        joinColumns = @JoinColumn(name = "student_id"),
        inverseJoinColumns = @JoinColumn(name = "course_id")
    )
    @Getter @Setter 
    @JsonIgnore
    private Set<Course> enrolledCourses = new HashSet<>();
}

User.java 

package com.example.demo.entity;

import java.time.LocalDate;
import java.time.Period;

import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.Transient;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.NonNull;
import lombok.RequiredArgsConstructor;
import lombok.Setter;

@Getter
@Setter
@RequiredArgsConstructor
@NoArgsConstructor
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String id;
    @NonNull private String name;
    @NonNull private String email;
    @NonNull private LocalDate dob;
    @Transient @NonNull private Integer age;

    public Integer getAge() {
        return Period.between(this.dob, LocalDate.now()).getYears();
    }
}

问题原因分析

  1. JPA继承注解缺失：User类作为实体父类，未标注@MappedSuperclass注解，JPA无法识别该类的映射元数据，导致子类Student的实体映射配置失效。
  2. age字段注解冲突：age字段是通过计算得到的瞬态字段，标注@NonNull会要求实例化时必须赋值，但该字段实际是动态计算的，会导致对象初始化异常。
  3. Student构造方法不规范：使用set方法初始化父类属性，而非调用父类构造方法，可能导致父类属性初始化不完整。

解决方案

修复User类

添加@MappedSuperclass注解，移除age字段的@NonNull：

package com.example.demo.entity;

import java.time.LocalDate;
import java.time.Period;

import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.MappedSuperclass;
import jakarta.persistence.Transient;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.NonNull;
import lombok.RequiredArgsConstructor;
import lombok.Setter;

@MappedSuperclass // 添加该注解，标识为JPA映射父类
@Getter
@Setter
@RequiredArgsConstructor
@NoArgsConstructor
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String id;
    @NonNull private String name;
    @NonNull private String email;
    @NonNull private LocalDate dob;
    @Transient private Integer age; // 移除@NonNull

    public Integer getAge() {
        return Period.between(this.dob, LocalDate.now()).getYears();
    }
}

修复Student构造方法

调用父类构造方法初始化属性：

public Student(String name, String email, LocalDate dob) {
    super(name, email, dob); // 直接调用父类带参构造
}

额外检查

  • 确保Teacher类后续修改时也遵循相同的继承规范，添加@Entity、@Table注解并继承User类。
  • 清理Maven缓存（执行mvn clean）后重新启动应用，避免缓存导致的异常。
