我已将 CDI 功能添加到server.xml文件<feature>cdi-1.2</feature>
中。
我的 Maven 模块包含文件夹内的beans.xml 。<module_name>/src/main/resources/META-INF
这是 beans.xml 内容:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
version="1.1" bean-discovery-mode="all">
</beans>
但是当我使用@Inject
注释时它不起作用,我的 bean 总是null
.
代码:
package ch.webapp.presentation;
...
@Path("/test/")
public class MyController {
@Inject
private MyService myService;
@GET
@Path("/foo/{count}")
@OAuthSecurity(scope = "login")
@Produces("application/json")
public Response news(@PathParam("count") int count) {
return Response
.ok(myService.getBar(count))
.build();
}
}
编辑:
那是我的豆子
package ch.webapp.service;
...
@RequestScoped
public class MyService {
public String getBar(int count) {
return "foo";
}
}
MFPJAXRSApplication
我通过扩展类来初始化 jax-rs
package ch.webapp;
...
public class AccountApplication extends MFPJAXRSApplication {
@Override
protected void init() throws Exception {
}
@Override
protected void destroy() throws Exception {
}
@Override
protected String getPackageToScan() {
return getClass().getPackage().getName();
}
}
环境细节:
Launching mfp (WebSphere Application Server 8.5.5.8/wlp-1.0.11.cl50820151201-1942) on Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_172-b11 (en_CH)
Console Product version: 8.0.0.00-20180717-175523
怎么了?
