hibernate连接sqlite的配置

首先需要导入sqlite的jar包

因为hibernate不支持sqlite，所以sqlite中的SQLiteDialect需要自己写。

自己建一个包，然后建一个SQLiteDialect.java

类中的代码如下：

 

package util;

import java.sql.Types;

import org.hibernate.Hibernate;
import org.hibernate.dialect.Dialect;
import org.hibernate.dialect.function.SQLFunctionTemplate;
import org.hibernate.dialect.function.StandardSQLFunction;
import org.hibernate.dialect.function.VarArgsSQLFunction;
import org.hibernate.type.IntegerType;
import org.hibernate.type.StringType;

public class SQLiteDialect extends Dialect {
    public SQLiteDialect() {
        super();
        registerColumnType(Types.BIT, "integer");
        registerColumnType(Types.TINYINT, "tinyint");
        registerColumnType(Types.SMALLINT, "smallint");
        registerColumnType(Types.INTEGER, "integer");
        registerColumnType(Types.BIGINT, "bigint");
        registerColumnType(Types.FLOAT, "float");
        registerColumnType(Types.REAL, "real");
        registerColumnType(Types.DOUBLE, "double");
        registerColumnType(Types.NUMERIC, "numeric");
        registerColumnType(Types.DECIMAL, "decimal");
        registerColumnType(Types.CHAR, "char");
        registerColumnType(Types.VARCHAR, "varchar");
        registerColumnType(Types.LONGVARCHAR, "longvarchar");
        registerColumnType(Types.DATE, "date");
        registerColumnType(Types.TIME, "time");
        registerColumnType(Types.TIMESTAMP, "timestamp");
        registerColumnType(Types.BINARY, "blob");
        registerColumnType(Types.VARBINARY, "blob");
        registerColumnType(Types.LONGVARBINARY, "blob");
        registerColumnType(Types.BLOB, "blob");
        registerColumnType(Types.CLOB, "clob");
        registerColumnType(Types.BOOLEAN, "integer");
        registerFunction("concat", new VarArgsSQLFunction(StringType.INSTANCE, "", "||", ""));
        registerFunction("mod", new SQLFunctionTemplate(IntegerType.INSTANCE, "?1 % ?2"));
        registerFunction("substr", new StandardSQLFunction("substr", StringType.INSTANCE));
        registerFunction("substring", new StandardSQLFunction("substr", StringType.INSTANCE));
    }

    public boolean supportsIdentityColumns() {
        return true;
    }

    /*
     public boolean supportsInsertSelectIdentity() {
     return true; // As specify in NHibernate dialect
     }
     */

    public boolean hasDataTypeInIdentityColumn() {
        return false; // As specify in NHibernate dialect
    }

    /*
     public String appendIdentitySelectToInsert(String insertString) {
     return new StringBuffer(insertString.length()+30). // As specify in NHibernate dialect
     append(insertString).
     append("; ").append(getIdentitySelectString()).
     toString();
     }
     */

    public String getIdentityColumnString() {
        // return "integer primary key autoincrement";
        return "integer";
    }

    public String getIdentitySelectString() {
        return "select last_insert_rowid()";
    }

    public boolean supportsLimit() {
        return true;
    }

    public String getLimitString(String query, boolean hasOffset) {
        return new StringBuffer(query.length() + 20).append(query).append(
                hasOffset ? " limit ? offset ?" : " limit ?").toString();
    }

    public boolean supportsTemporaryTables() {
        return true;
    }

    public String getCreateTemporaryTableString() {
        return "create temporary table if not exists";
    }

    public boolean dropTemporaryTableAfterUse() {
        return false;
    }

    public boolean supportsCurrentTimestampSelection() {
        return true;
    }

    public boolean isCurrentTimestampSelectStringCallable() {
        return false;
    }

    public String getCurrentTimestampSelectString() {
        return "select current_timestamp";
    }

    public boolean supportsUnionAll() {
        return true;
    }

    public boolean hasAlterTable() {
        return false; // As specify in NHibernate dialect
    }

    public boolean dropConstraints() {
        return false;
    }

    public String getAddColumnString() {
        return "add column";
    }

    public String getForUpdateString() {
        return "";
    }

    public boolean supportsOuterJoinForUpdate() {
        return false;
    }

    public String getDropForeignKeyString() {
        throw new UnsupportedOperationException(
                "No drop foreign key syntax supported by SQLiteDialect");
    }

    public String getAddForeignKeyConstraintString(String constraintName,
            String[] foreignKey, String referencedTable, String[] primaryKey,
            boolean referencesPrimaryKey) {
        throw new UnsupportedOperationException(
                "No add foreign key syntax supported by SQLiteDialect");
    }

    public String getAddPrimaryKeyConstraintString(String constraintName) {
        throw new UnsupportedOperationException(
                "No add primary key syntax supported by SQLiteDialect");
    }

    public boolean supportsIfExistsBeforeTableName() {
        return true;
    }

    public boolean supportsCascadeDelete() {
        return false;
    }
}

然后需要配置hibernate.cfg.xml

 

配置文件代码如下：

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC  
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">  
  
<hibernate-configuration>  
    <session-factory >  
        <property name="hibernate.connection.driver_class">org.sqlite.JDBC</property>  
	<property name="hibernate.connection.url">jdbc:sqlite://D:/work.db3</property> 
	<property name="hibernate.dialect">util.SQLiteDialect</property>
	<property name="hibernate.show_sql">true</property>  
	<property name="hibernate.format_sql">true</property>  
	
    <mapping resource="work.hbm.xml"/> 
    </session-factory>  
</hibernate-configuration>  

<property name="hibernate.dialect">util.SQLiteDialect</property>中的值为自己建的包中的SQLiteDialect.java的路径
