Spring 3.2 @Configurable dan @Autowire gagal menyuntikkan apa pun

Saya ingin memasukkan instance SecureRandom ke dalam kelas @Entity, tetapi ketika saya memeriksa nilainya saat menjalankan Tomcat versi debugger, saya hanya melihat nilai nol di sana. Saya tidak mendapatkan pesan kesalahan apa pun.

Saya telah menempatkan spring-instrument-Tomcat-3.2.5.RELEASE.jar ke dalam C:\Apache-Tomcat-7.0.40\lib dan sepertinya diambil dengan baik.

File Gradle.build

Hanya ketergantungannya

Kelas entitas

Saya menghapus beberapa tambahan untuk membuat contoh ini lebih jelas.

@Entity
@Configurable(preConstruction = true, autowire = Autowire.BY_TYPE)
public class Invitation {

    @Id
    @GeneratedValue
    private int id;

    @Transient
    @Autowired
    private SecureRandom random;

    public Invitation(User owner, String inviteeEmail, String accessCode) {
        if(accessCode == null) {
            this.accessCode = generateAlphanumericAccessCode();
        } else {
            this.accessCode = accessCode;
        }
        this.owner = owner;
        this.inviteeEmail = inviteeEmail;
    }

    private String generateAlphanumericAccessCode() {
        return new BigInteger(130, random).toString(32);
    }

}

Kelas Konfigurasi Java

Sekali lagi, hapus tambahan untuk memperjelasnya.

@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = RootContextConfig.class)
@EnableTransactionManagement
@EnableWebSecurity
@EnableAsync
@EnableSpringConfigured
@EnableLoadTimeWeaving(aspectjWeaving = EnableLoadTimeWeaving.AspectJWeaving.ENABLED)
public class RootContextConfig extends WebMvcConfigurerAdapter {

    @Bean
    public SecureRandom secureRandom() {
        return new SecureRandom();
    }
}

Context.xml (terletak di webapp/META-INF)

Aplikasi web saya diterapkan ke konteks root dalam produksi dan pengembangan.

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
</Context>
