mysql - Hibernate Spring 编码字符集错误 [UTF-8]

Question

开发环境:

• Spring 4.2 倍
• hibernate 4.3.11
• Tomcat 8 服务器
• MySQL 5.4

在更改为 Hibernate 之前，插入、检索和显示字符没有问题。然而，在我的 DAO 中进行更改以奇怪地使用 Hibernate 之后，我似乎无法将正确的字符插入到 MySQL 数据库中。

我已经确保 MySQL Schema 确实可以通过使用查询“INSERT INTO spring_normalize.offers (text , users_username) VALUES ('ölm', 'lalalal');"index.jsp 上的输出是正确的。

我修改了我的 hibernate 配置

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hibernate.connection.useUnicode">true</prop><!-- added -->
                <prop key="hibernate.connection.characterEncoding">UTF-8</prop><!-- added -->
                <prop key="hibernate.connection.charSet">UTF-8</prop><!-- added -->

            </props>
        </property>

        <property name="packagesToScan">
            <list>
                <value>com.caveofprogramming.pring.web.dao</value>
            </list>
        </property>
    </bean>

这似乎行不通

检查 list :

1. 数据库架构设置为 utf8 - utf8_unicode_ci。
2. Hibernat 配置将字符集添加到 UTF-8。
3. jsp 页面 language="java"contentType="text/html; charset=UTF-8" pageEncoding="UTF-8
4. 我还按照这篇文章的建议添加了过滤器... Spring MVC UTF-8 Encoding

* 更新 * 这是我的 bean 和 DAO

表格

<sf:form method="POST" action="${pageContext.request.contextPath}/docreate" commandName="offer">
    <sf:input type="text" path="id" name="id" readonly="true" />
    <label for="text">Text</label>
    <sf:textarea id="text" name="text" row="3" path="text"></sf:textarea>
    <sf:errors path="text" cssClass="error"></sf:errors>
    <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
    <input type="submit" value="Submit">

</sf:form>

报价

@Entity
@Table(name="offers")
 public class Offer{
  @Id
  private int id;
  private String text;

  getIn(){}
  .....
}

OfferDao

public class OfferDao{
   @Autowired
   private SessionFactory sessionFactory;

   public Session currentSession(){
    return sessionFactory.getCurrentSession();
   }

   public boolean create(Offer offer){
     int hiberReturn =(int) currentSession().save(offer);

     return hiberReturn >= 0;
   }
}  

非常感谢任何能提供帮助的人......真的......非常感谢

对于 Java (JDBC):

?useUnicode=yes&characterEncoding=UTF-8 in the getConnection() call.

对于 Hikari(也许):

spring.jpa.properties.hibernate.connection.characterEncoding=utf-8  
spring.jpa.properties.hibernate.connection.CharSet=utf-8  
spring.jpa.properties.hibernate.connection.useUnicode=true

Spring/Hibernate 过滤器:

<form accept-charset="UTF-8">

Spring/Hibernate: <property name="url"
    value="jdbc:mysql://localhost:3306/miniprojetjee?useUnicode=true
           &connectionCollation=utf8_general_ci
           &characterSetResults=utf8&characterEncoding=utf-8"/>

"Spring": @RequestMapping(value = "/getRegion2",
    produces={"application/json; charset=UTF-8"},method = RequestMethod.GET)
