Question

我在使用Hibernate从表单保存数据时遇到问题，基本上编码出错了，所以奇怪的字符被保存在数据库中，并在表单输入中填充。这是我到目前为止准备的配置：

web.xml中的

 <filter>
    <filter-name>SetCharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</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>

在applicationContext.xml中

（尝试了两种模式'UTF-8'和'utf8'）

<property name="url" value="jdbc:postgresql://localhost:5432/mydb?characterEncoding=UTF-8" />

...

<property name="hibernateProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQL9Dialect</prop>
                <prop key="hibernate.connection.CharSet">utf8</prop>
                <prop key="hibernate.connection.characterEncoding">utf8</prop>
                <prop key="hibernate.cache.use_query_cache">true</prop>
                <prop key="hibernate.cache.use_second_level_cache">true</prop>
                <prop key="hibernate.cache.region.factory_class">
                    org.hibernate.cache.ehcache.EhCacheRegionFactory
                </prop>
                <prop key="hibernate.connection.useUnicode">true</prop>
                <prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop>
                <prop key="show_sql">true</prop>

                <prop key="hibernate.c3p0.min_size">5</prop>
                <prop key="hibernate.c3p0.max_size">20</prop>
                <prop key="hibernate.c3p0.timeout">300</prop>
                <prop key="hibernate.c3p0.max_statements">50</prop>
                <prop key="hibernate.c3p0.idle_test_period">3000</prop>
            </props>
</property>

的pom.xml

<properties>
        <spring.version>4.1.2.RELEASE</spring.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

数据库，jsp文件和项目也有ut8编码，我也将URIEncoding =“UTF-8”添加到server.xml中的连接器配置中。我还需要添加什么或者我做错了什么？

Answer 1

您可以设置断点并检查从字节（UTF-8）到Unicode的编码是否正确完成。接下来要做的是检查数据库/表的排序规则。创建数据库/表时，您指定了排序规则，相当于字符集（通常在安装期间选择默认值），如果这不支持您存储的字符，则可能会出现垃圾。

Answer 2

解决方案是：

@Order(1)
public class SpringSecurityInitializer extends AbstractSecurityWebApplicationInitializer {

    @Override
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
        FilterRegistration.Dynamic characterEncodingFilter = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
        characterEncodingFilter.setInitParameter("encoding", "UTF-8");
        characterEncodingFilter.setInitParameter("forceEncoding", "true");
        characterEncodingFilter.addMappingForUrlPatterns(null, false, "/*");
    }

}
