我需要在JSF组件中使用自定义html属性,为此我发现的唯一解决方案是使用JSF 2.2,这样:

<f:passThroughAttribute name="data-toggle" value="modal" />

问题是我正在使用Spring + Tomcat而我无法改变这个因为我没有时间.每次我启动我的服务器时都会出现以下错误:

Informações: CDI @ViewScoped manager unavailable
java.lang.NoClassDefFoundError: javax/enterprise/context/spi/Contextual

我知道这是因为我不使用CDI,但正如我所说,由于时间的原因,我无法从Spring改为CDI.

我怎么解决这个问题 ？我必须使用JSF 2.2(因为自定义html属性)和Spring.

解决了:

这个问题解决了,我降级到JSF 2.2.6并且错误停止了.

好吧,我有一个带@Service注释的类和一些奇怪的发生器:当我把注释@Transaction放在某些方法中我无法启动tomcat服务器时,我得到错误:"无法自动装配......"在另一个类中当我使用我的@Autowired,但当我删除@Transaction一切正常.

我的标题是:

@Service(value = "caixaBO")
public class CaixaBOImpl extends BasicBOImpl {

我的方法签名是:

@Transactional(propagation = Propagation.REQUIRED)
public void movimentarCaixaPaciente(String descricao, double valor,
        Paciente paciente) {

当我使用@Autowired CaixaBOImpl caixaBO时,由于注释@Transaction,我在tomcat初始化时出错.

编辑1:

1 - 我在applicationContext.xml中有transactionManager,看看:

<!-- Configuracao do gerente de transacoes do Spring -->
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

2 - 我在pom.xml中有CGLIB,看看:

<dependency>
            <groupId>cglib</groupId>
            <artifactId>cglib-nodep</artifactId>
            <version>2.2.2</version>
        </dependency>

我的项目工作,有些类有奇怪的错误,如下所示:"JOIN FETCH表达式不能用标识变量定义." 当我运行"Maven - > Update Project"时,"JOIN FETCH .."中的错误消失但我继续不启动我的服务器.

好吧,我知道我必须从我的对象中选择一个独特的字段,比如ID.然后我的rowKey是"item.id".这在dataTable中加载所有itens时工作正常,但是如果我添加一个新项(此对象在数据库中没有持久化)并且具有空ID,则它在我的dataTable中不会显示.

这是什么解决方案？我只是可以使用ID作为rowKey但有时我需要添加一个具有NULL ID的新对象(因为这还没有在数据库上保留).

看看我的代码:

<p:dataTable rowKey="#{item.id}" var="item"
                    value="#{orcamentoMB.itens}"
                    emptyMessage="Não foi encontrado nenhum registro"
                    id="dataTableItens"
                    selection="#{orcamentoMB.selectedItemOrcamento}"
                    selectionMode="single" rowIndexVar="rowIndex"
                    rowStyleClass="#{(rowIndex mod 2) eq 0 ? 'first-row' : 'second-row'}">

好吧,我是CodeIgniter Framework的新手,我正在尝试构建一个通用的Model Class.看到:

class Basic_Model extends CI_MODEL {

    function __construct() {
        // Call the Model constructor
        parent::__construct();
    }

}

我想基于Basic_Model扩展所有模型,如下所示:

class Pagina_Model extends Basic_Model {

    function __construct() {
        // Call the Model constructor
        parent::__construct();
    }

}

问题是当我尝试从Controller调用"pagina_model"时出现以下错误:

Fatal error: Class 'Basic_Model' not found in /var/www/myproject/application/models/pagina_model.php on line 12

如果我在控制器中使用"basic_model"一切正常.

编辑1:

我在"/ application/core"中创建了一个名为MY_Basic_Model.php的文件,并将类名更改为"MY_Basic_Model".但我得到了错误:

Fatal error: Class 'MY_Basic_Model' not found in /var/www/myproject/application/models/pagina_model.php on line 12
