如何通过数据库中的 Spring Hibernate 在 TextBox 中插入古吉拉特语？

Question

我正在尝试使用 Java Spring Hibernate 项目将古吉拉特语存储在 postgreSQL 数据库中，但它存储的是这样的东西

મà«àª¦à«àª¨àª¾ àªàª¯-પરાàªàª¯ પાàªàª³ ઠવà«àª¯àªà«àª¤àª¿àª¨à«àª àªà«àªà«àª

而不是

મોદીના જય-પરાજય પાછળ આ વ્યક્તિનું ભેજું

在我的数据库中，编码是 UTF-8，如果我直接在 postgreSQL 中复制粘贴，它会正确存储，但从 Web 应用程序中的 html 表单中它无法正确存储。

以下是我的hibernate.hbm.cfg 文件

<?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">

    <mapping class="com.models.Video" />
    <mapping class="com.models.Contact" />
    <mapping class="com.models.Heading" />
</session-factory>

</hibernate-configuration>

我也用过

%@page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" % >

在 jsp 页面中，这会使古吉拉特语正确显示，但在表单提交中仍然存在问题。

在模型类中

package com.models;

import static javax.persistence.GenerationType.IDENTITY;

import java.io.UnsupportedEncodingException;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.UniqueConstraint;
import javax.validation.Valid;
import javax.validation.constraints.Pattern;

import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.NotBlank;
import org.springframework.format.annotation.DateTimeFormat;

import com.sun.istack.internal.NotNull;

@Entity
@Table(name = "tbl_heading_info", uniqueConstraints = {
    @UniqueConstraint(columnNames = "id")})
public class Heading {
private int id;

@NotNull
@NotBlank
private String message;

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "id", unique = true, nullable = false)
public int getId() {
    return id;
}

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

@Column(name = "message", nullable = false)
public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
    /*byte ptext[] = null;
    try {
        ptext = message.getBytes("ISO_8859_1");
    } catch (UnsupportedEncodingException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    try {
        String value = new String(ptext, "UTF-8");
        this.message=value;
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } */

}

}

我也在 web.xml 中添加了过滤器

<filter>
<filter-name>SetCharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
    <param-name>encoding</param-name>
    <param-value>UTF8</param-value>
</init-param>
<init-param>
    <param-name>forceEncoding</param-name>
    <param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>SetCharacterEncodingFilter</filter-name>
<url-pattern>*</url-pattern>
</filter-mapping>

上周我不得不面对这个，试试这个。 使用 'definitivo' 具有 textBox.getText() 并转换为 UTF-8

byte ptext[] = definitivo.getBytes("ISO_8859_1");

字符串值 = new String(ptext, "UTF-8");
