錯誤org.springframework.beans.factory.BeanCreationException：創建類路徑資源中定義的名稱為“ dataSource”的bean時出錯

Question

我嘗試使用JDBC制作Spring Embedded Database HSQL Exmple，但出現錯誤，我的代碼，consol輸出和gist鏈接都在下面。如何修復此項目，謝謝幫助。

要點代碼

 package com.fatih.model;

public class Calisan {
private String ad;
private String soyad;
public String getAd() {
    return ad;
}
public void setAd(String ad) {
    this.ad = ad;
}
public String getSoyad() {
    return soyad;
}
public void setSoyad(String soyad) {
    this.soyad = soyad;
}

public Calisan() {
    // TODO Auto-generated constructor stub
}
public Calisan(String ad, String soyad) {
    super();
    this.ad = ad;
    this.soyad = soyad;
}
@Override
public String toString() {
    return "Calisan [ad=" + ad + ", soyad=" + soyad + "]";
}

Answer 1

好像您缺少spring-dao.jar。

nested exception is java.lang.NoClassDefFoundError: org/springframework/dao/DataAccessException

確保您的類路徑中有jar文件。

Answer 2

請注意，在appconfig.xml（應用程序上下文）中，您尚未定義任何DataSource對象。 您定義了一個DataSourceFactory。 那不一樣。

在您的類中，您將注入一個DataSource對象。

因此，在您的appconfig.xml（應用程序上下文）中，應替換為

<bean id="dataSource"
        class="org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseFactoryBean">
    <property name="databasePopulator" ref="populator" />
    <property name="databaseType" value="HSQL" />
</bean>
<bean id="populator"
        class="org.springframework.jdbc.datasource.init.ResourceDatabasePopulator">
    <property name="scripts">
        <list>
            <value>schema.sql</value>
            <value>data.sql</value>
        </list>
    </property>
</bean>

有了這個

<!-- jdbc:hsqldb:mem:dataSource -->
<jdbc:embedded-database id="dataSource" type="HSQL">
    <jdbc:script location="classpath:schema.sql" />
    <jdbc:script location="classpath:data.sql" />
    <!-- assuming you have your sql scripts in src/main/resources -->
</jdbc:embedded-database>
