解決springdatajpa 在解析實體類的字段時候駝峯自動轉爲下劃線問題 問題描述

springboot 在配置jpa時，利用idea自帶工具逆向工程生成實體類，結果在調用findOne的時候，報錯
錯誤內容如下所示：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'shasset0_.asset_type_name' in 'field list'

實體類片段

@Entity
@Table(name = "sh_asset")
public class ShAsset {
    private String id;
    private String assetTypeName;
    private String assetName;
    private String assetCode;
    private String assetType;
    private String area;
    private String orgname;
    private String username;
    private String contract;
    private String address;
    private String recorderId;
    private String recorderName;
    private Timestamp recorddate;
    private String iPadd;
    private Timestamp editTime;
    private Integer assetStatus;
    private String maCadd;
    private Date userDate;
    private Integer leaseState;

    @Id
    @Column(name = "id")
    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    @Basic
    @Column(name = "asset_typeName")
    public String getAssetTypeName() {
        return assetTypeName;
    }

    public void setAssetTypeName(String assetTypeName) {
        this.assetTypeName = assetTypeName;
    }

問題原因

由於springboot 中jpa默認自動將實體類中的駝峯命名轉化爲下劃線隔開的方式進行數據庫查詢，將字段getAssetTypeName自動轉換爲 asset_type_name導致數據庫找不到該字段

解決辦法

在配置文件中取消自動將駝峯命名轉爲下劃線形式

    hibernate:
      naming:
