spring data jpa 插入报错

Question

我用spring data jpa做了个持久化的操作,下面是实体类和单元测试

@Entity
@Table(name = "doaj_article_content", schema = "spider")
public class DoajArticleContentEntity {
    private String id;
    private String articleTitle;
    private String journalTitle;
    private String issn;
    private String publisher;
    private String lastUpdated;
    private String createdDate;
    private String lccSubjectCategory;
    private String countryOfPublisher;
    private String languageOfFulltext;
    private String authors;
    private String endPage;
    private String startPage;
    private String articleAbstract;
    private String doi;
    private String fulltext;

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

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

    @Basic
    @Column(name = "article_title")
    public String getArticleTitle() {
        return articleTitle;
    }

    public void setArticleTitle(String articleTitle) {
        this.articleTitle = articleTitle;
    }

    @Basic
    @Column(name = "journal_title")
    public String getJournalTitle() {
        return journalTitle;
    }

    public void setJournalTitle(String journalTitle) {
        this.journalTitle = journalTitle;
    }

    @Basic
    @Column(name = "issn")
    public String getIssn() {
        return issn;
    }

    public void setIssn(String issn) {
        this.issn = issn;
    }

    @Basic
    @Column(name = "publisher")
    public String getPublisher() {
        return publisher;
    }

    public void setPublisher(String publisher) {
        this.publisher = publisher;
    }

    @Basic
    @Column(name = "last_updated")
    public String getLastUpdated() {
        return lastUpdated;
    }

    public void setLastUpdated(String lastUpdated) {
        this.lastUpdated = lastUpdated;
    }

    @Basic
    @Column(name = "created_date")
    public String getCreatedDate() {
        return createdDate;
    }

    public void setCreatedDate(String createdDate) {
        this.createdDate = createdDate;
    }

    @Basic
    @Column(name = "lcc_subject_category")
    public String getLccSubjectCategory() {
        return lccSubjectCategory;
    }

    public void setLccSubjectCategory(String lccSubjectCategory) {
        this.lccSubjectCategory = lccSubjectCategory;
    }

    @Basic
    @Column(name = "country_of_publisher")
    public String getCountryOfPublisher() {
        return countryOfPublisher;
    }

    public void setCountryOfPublisher(String countryOfPublisher) {
        this.countryOfPublisher = countryOfPublisher;
    }

    @Basic
    @Column(name = "language_of_fulltext")
    public String getLanguageOfFulltext() {
        return languageOfFulltext;
    }

    public void setLanguageOfFulltext(String languageOfFulltext) {
        this.languageOfFulltext = languageOfFulltext;
    }

    @Basic
    @Column(name = "authors")
    public String getAuthors() {
        return authors;
    }

    public void setAuthors(String authors) {
        this.authors = authors;
    }

    @Basic
    @Column(name = "end_page")
    public String getEndPage() {
        return endPage;
    }

    public void setEndPage(String endPage) {
        this.endPage = endPage;
    }

    @Basic
    @Column(name = "start_page")
    public String getStartPage() {
        return startPage;
    }

    public void setStartPage(String startPage) {
        this.startPage = startPage;
    }

    @Basic
    @Column(name = "article_abstract")
    public String getArticleAbstract() {
        return articleAbstract;
    }

    public void setArticleAbstract(String articleAbstract) {
        this.articleAbstract = articleAbstract;
    }

    @Basic
    @Column(name = "doi")
    public String getDoi() {
        return doi;
    }

    public void setDoi(String doi) {
        this.doi = doi;
    }

    @Basic
    @Column(name = "fulltext")
    public String getFulltext() {
        return fulltext;
    }

    public void setFulltext(String fulltext) {
        this.fulltext = fulltext;
    }

   
}

测试 save方法报错:

    @Test
    public void test2() {

        DoajArticleContentEntity entity = new DoajArticleContentEntity();
        entity.setId("test");

        Optional<DoajArticleContentEntity> test = repository.findById("test1");//正常

         repository.save(entity);//报错



    }

如上面代码,查询时正常,但是保存时就会出现异常,查了好久,不知道什么原因,希望知情这解惑,感激不尽,谢谢.

完整异常信息如下:

Answer 1

near 'fulltext, issn, journal_title, language_of_fulltext, last_updated, lcc_subject_c' at line 1。。。。考虑一下mysql关键字冲突问题，fulltext这个字段
