Question

如何定义此列？我试过了：

    //@Column(name="GLN_NM", nullable=false, length=255)
    //@Column(name="GLN_NM", nullable=false)
    //@Column(name="GLN_NM", nullable=false, columnDefinition="varchar(255)")
    //@Column(name="GLN_NM", nullable=false, type="text")
    //@Column(name="GLN_NM", nullable=false, columnDefinition="text")
    //@Column(name="GLN_NM", nullable=false, columnDefinition="TextType")
    @Column(name="GLN_NM", length=255)
    private String glnNm;

我看到的问题是由以下原因引起的：org.hibernate.tool.schema.spi.SchemaManagementException：模式验证：表[gs1_gpc]中的列[GPC_NM]中遇到错误的列类型;找到[text（Types＃LONGVARCHAR）]，但期待[longtext（Types＃CLOB）]

我已阅读https://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/Hibernate_User_Guide.html和几篇文章： 6207788， 16641758， 40884306， 28588311， 26774193， 3868096， 12398597， 8355669， 12672764， 10043556， 1262174

打开产品数据（http://www.product-open-data.com/download/）将表定义为：

"Field"         "Type"      "Null"  "Key"   "Default"
"GCP_CD"    "varchar(13)"   "NO"    "PRI"   \N
"GLN_CD"    "varchar(13)"   "NO"    ""  \N
"GLN_NM"    "varchar(255)"  "NO"    ""  \N
"GLN_ADDR_02"   "varchar(38)"   "NO"    ""  \N
"GLN_ADDR_03"   "varchar(38)"   "NO"    ""  \N
"GLN_ADDR_04"   "varchar(38)"   "NO"    ""  \N

"GLN_LAST_CHANGE" "varchar(10)" "NO"    ""  \N
"GLN_PROVIDER"  "varchar(13)"   "NO"    ""  \N

Answer 1

没有必要指定columnDefinition，如columnDefinition =＆＃34; text＆＃34;在你的pojo。

而只是放入你的pojo： @Column（名称=＆＃34; GLN_NM＆＃34） private String glnNm;

在你的mysql中将该列定义为： varchar（256）或LongText或MediumText根据您的要求。

Answer 2

正如上面的评论所述，GLN_NM列工作得很好。麻烦制造者是GPC_NM列（未包含在OP原始代码中）

Hibernate无法映射MySQL varchar（255）
