当我搜索这个问题时，有人说我们应该使用springframework.orm.hibernate4而不是springframework.orm.hibernate3。我做到了但我仍然得到同样的例外。

有人可以帮我识别我在这里缺少的东西。

由于

Answer 1

注意：在从Hibernate 3到Hibernate 4的更改中删除了 org.hibernate.cache.Provider。

如果你使用hibernate 3，你可能会得到java.lang.ClassNotFoundException: org.hibernate.cache.CacheProvider。如果您更改为休眠4，则无法获得，但您首先应添加hibernate4.jar和spring-orm.jar。

Answer 2

听起来你在项目设置中缺少hibernate依赖：

引起：java.lang.ClassNotFoundException：org.hibernate.cache.CacheProvider

尝试下载hibernate-core.jar并添加到项目类路径中。

如果您使用Maven，只需将以下依赖项添加到项目的pom.xml中：

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-core</artifactId>
  <version>${hibernate.version}</version>
</dependency>

希望有所帮助。

Answer 3

您正在将 HibernateTransactionManager 注入 DAO 类而不是 HibernateTemplate 。请检查您的文件配置。

Answer 4

此解决方案也适用于我：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>3.6.10.Final</version>
</dependency>

在我的情况下，我已经有了hibernate-entitymanager依赖，但是试图使用最新版本的hibernate - 4.3.1.Final。不知道为什么降级在这里是必要的，但很可能是“简单的春天JPA实用工程”我在STS 3.5.0.M2的基础上也有点过时了？

Answer 5

您必须更改弹簧配置文件。
改变：

$(function() { // General Configuration of the plugin var config = { position_left : true, // true for left || false for right negative_vote : true, // true for negative votes || false for positive only vote_bar : true, // display a small bar under the vote buttons // button config icon_plus : '<img src="http://i18.servimg.com/u/f18/18/21/41/30/plus10.png" alt="+"/>', icon_minus : '<img src="http://i18.servimg.com/u/f18/18/21/41/30/minus10.png" alt="-"/>', // language config title_plus : 'Like %{USERNAME}\'s post', title_minus : 'Dislike %{USERNAME}\'s post', title_like_singular : '%{VOTES} person likes %{USERNAME}\'s post', title_like_plural : '%{VOTES} people like %{USERNAME}\'s post', title_dislike_singular : '%{VOTES} person dislikes %{USERNAME}\'s post', title_dislike_plural : '%{VOTES} people dislike %{USERNAME}\'s post', title_vote_bar : '%{VOTES} people liked %{USERNAME}\'s post %{PERCENT}' }, // function bound to the onclick handler of the vote buttons submit_vote = function() { var next = this.nextSibling, // the counter next to the vote button that was clicked box = this.parentNode, bar = box.getElementsByTagName('DIV'), vote = box.getElementsByTagName('A'), mode = /eval=plus/.test(this.href) ? 1 : 0, i = 0, j = vote.length, pos, neg, percent; // submit the vote asynchronously $.get(this.href, function() { next.innerHTML = +next.innerHTML + 1; // add to the vote count next.title = next.title.replace(/(\d+)/, function(M, $1) { return +$1 + 1 }); pos = +vote[0].nextSibling.innerHTML; neg = vote[1] ? +vote[1].nextSibling.innerHTML : 0; percent = pos == 0 ?

Please contact the support for further assistance.'); return; } for (; i < j; i++) { post = $(vote[i]).parentsUntil('.post').parent()[0]; bar = $('.vote-bar', vote[i])[0]; // vote bar button = $('.vote-button', vote[i]); // plus and minus buttons pseudo = $(vdata.name, post).text() || 'MISSING_STRING'; // username of the poster ul = $(vdata.actions, post)[0]; // post actions li = document.createElement(vdata.tag); // vote system container li.className = 'fa_reputation'; if (li.tagName == 'SPAN') li.style.display = 'inline-block'; // calculate votes if (bar) { total = +bar.title.replace(/.*?\((\d+).*/, '$1'); percent = +bar.title.replace(/.*?(\d+)%.*/, '$1'); n_pos = Math.round(total * (percent / 100)); n_neg = total - n_pos; } else { n_pos = 0; n_neg = 0; } // set up negative and positive titles with the correct grammar, votes, and usernames title_pos = (n_pos == 1 ? config.title_like_singular : config.title_like_plural).replace(/%\{USERNAME\}/g, pseudo).replace(/%\{VOTES\}/g, n_pos); title_neg = (n_neg == 1 ? config.title_dislike_singular : config.title_dislike_plural).replace(/%\{USERNAME\}/g, pseudo).replace(/%\{VOTES\}/g, n_neg); // define the vote counts li.innerHTML = '<span class="fa_count fa_positive" title="' + title_pos + '">' + n_pos + '</span>' + (config.negative_vote ? ' <span class="fa_count fa_negative" title="' + title_neg + '">' + n_neg + '</span>' : ''); span = li.getElementsByTagName('SPAN'); // get the vote count containers for use as insertion points // create positive vote button plus = document.createElement('A'); plus.href = button[0] ? button[0].firstChild.href : '#'; plus.onclick = button[0] ? submit_vote : function() { return false }; plus.className = 'fa_vote' + (button[0] ? '' : 'd') + ' fa_plus'; plus.innerHTML = config.icon_plus; plus.title = (button[0] ? config.title_plus : title_pos).replace(/%\{USERNAME\}/g, pseudo); span[0] && li.insertBefore(plus, span[0]); // create negative vote button if (config.negative_vote) { minus = document.createElement('A'); minus.href = button[1] ? button[1].firstChild.href : '#'; minus.onclick = button[1] ? submit_vote : function() { return false }; minus.className = 'fa_vote' + (button[1] ?

，并改变：

"org.springframework.orm.hibernate3.HibernateTemplate"为LocalSessionFactoryBean bean

它会起作用。

Answer 6

这可能是因为您在春季配置文件中为“ sessionFactory”使用的是“ org.springframework.orm.hibernate3.LocalSessionFactoryBean”而不是“ org.springframework.orm.hibernate4.LocalSessionFactoryBean”。

Answer 7

如果您正在使用Maven，请尝试将其放入POM文件中：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>3.6.10.Final</version>
</dependency>

这对我有用。
