当我使用基于Java的Java配置我的JNDI时。春天4.2.5。

但是，如果我使用JndiObjectFactoryBean进行配置。当我想获取时datasource，该对象将为null。

@Bean
    public DataSource dataSource(){
        JndiObjectFactoryBean jndiObjectFactoryBean =new JndiObjectFactoryBean();
        jndiObjectFactoryBean.setJndiName("jdbc/SpittrDS");
        jndiObjectFactoryBean.setResourceRef(true);
        jndiObjectFactoryBean.setProxyInterface(DataSource.class);
        return (DataSource) jndiObjectFactoryBean.getObject();  //NULL!!!
    }

但是如果对此更改方法，它将很好地工作。

@Bean
    public DataSource dataSource(){
        final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        DataSource dataSource = dsLookup.getDataSource("java:comp/env/jdbc/SpittrDS");
        return dataSource;
    }

我不知道问题出在哪里。

当我使用这个'依赖'时,一切都很好.该应用运行.

应用程序依赖项:

dependencies {

    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
    compile 'com.android.support:recyclerview-v7:23.0.1'
    compile 'org.jsoup:jsoup:1.7.2'
    compile 'com.mcxiaoke.volley:library:1.0.19'
}

但是当我在这个应用程序中添加一个java模块依赖项时,它会抛出错误:

错误:任务':app:dexDebug'的执行失败.com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException:进程'命令'D:\ Java\jdk1.8.0_45\bin\java.exe''以非零退出值结束1

像这样

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 23
        buildToolsVersion "23.0.1"

        defaultConfig {
            applicationId "three.com.materialdesignexample"
            minSdkVersion 15
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
            multiDexEnabled true
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }

    }

    dependencies {

        compile project(':securitycode')
        compile 'com.android.support:appcompat-v7:23.0.1'
        compile 'com.android.support:design:23.0.1'
        compile 'com.android.support:recyclerview-v7:23.0.1'
        compile 'org.jsoup:jsoup:1.7.2'
        compile 'com.mcxiaoke.volley:library:1.0.19'
    }

我的Java模块依赖项什么都没有

apply plugin: 'java'

dependencies { …
