@ivar_grimstad Øredev 2014 Mixing Spring 4 with Java EE 7

@ivar_grimstad Øredev 2014 Java EE 7 vs Spring 4

@ivar_grimstad Øredev 2014 Spring 4 vs Java EE 7

@ivar_grimstad Øredev 2014 Java EE 7 Container Java EE 7
Application (WAR) bean bean @Inject

@ivar_grimstad Øredev 2014 Spring 4 Container Spring 4 Application (WAR)
Spring 4 Context bean bean @Autowired

@ivar_grimstad Øredev 2014 So What about Mixing Spring and Java
EE?

@ivar_grimstad Øredev 2014 Java EE 7 -> Spring 4 Container
Java EE 7 Application (WAR) bean Spring 4 Context bean bean bean @Inject @Inject @Autowired

@ivar_grimstad Øredev 2014 Spring 4 -> Java EE 7 Container
Spring 4 Application (WAR) bean Spring 4 Context bean bean bean @Autowired @Inject @Autowired

@ivar_grimstad Øredev 2014 DEMO !

@ivar_grimstad Øredev 2014 Summary

@ivar_grimstad Øredev 2014 Spring 4 and Java EE 7 solves
the same problem

@ivar_grimstad Øredev 2014 Java EE 7 require less conﬁguration and
dependencies

@ivar_grimstad Øredev 2014 Spring 4 is more portable

@ivar_grimstad Øredev 2014 Using Spring 4 from Java EE is
safer

@ivar_grimstad Øredev 2014 Mixing is possible

@ivar_grimstad Øredev 2014 …but…

@ivar_grimstad Øredev 2014 Favor one framework over mixing

@ivar_grimstad Øredev 2014 Use Cases

@ivar_grimstad Øredev 2014 Container Java EE 7 Application (WAR) bean
Spring 4 Context bean bean bean @Inject @Inject @Autowired Use Spring Component

@ivar_grimstad Øredev 2014 Container Java EE 7 Application (WAR) bean
Spring 4 Context bean bean bean @Inject @Inject @Autowired Migration

@ivar_grimstad Øredev 2014 Container Spring 4 Application (WAR) bean Spring
4 Context bean bean bean @Autowired @Inject @Autowired Migration
