copyright notice that is included in or attached to the work
38+
(an example is provided in the Appendix below).
39+
40+
"Derivative Works" shall mean any work, whether in Source or Object
41+
form, that is based on (or derived from) the Work and for which the
42+
editorial revisions, annotations, elaborations, or other modifications
43+
represent, as a whole, an original work of authorship. For the purposes
44+
of this License, Derivative Works shall not include works that remain
45+

46+
the Work and Derivative Works thereof.
47+
48+
"Contribution" shall mean any work of authorship, including

to that Work or Derivative Works thereof, that is intentionally
51+
submitted to Licensor for inclusion in the Work by the copyright owner
52+
or by an individual or Legal Entity authorized to submit on behalf of
53+
the copyright owner. For the purposes of this definition, "submitted"

61+
62+
"Contributor" shall mean Licensor and any individual or Legal Entity

66+
2. Grant of Copyright License. Subject to the terms and conditions of
67+
this License, each Contributor hereby grants to You a perpetual,
68+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
69+
copyright license to reproduce, prepare Derivative Works of,
70+
publicly display, publicly perform, sublicense, and distribute the
71+
Work and such Derivative Works in Source or Object form.
72+
73+
3. Grant of Patent License. Subject to the terms and conditions of

79+
by such Contributor that are necessarily infringed by their
80+
Contribution(s) alone or by combination of their Contribution(s)
81+
with the Work to which such Contribution(s) was submitted. If You
82+
institute patent litigation against any entity (including a
83+
cross-claim or counterclaim in a lawsuit) alleging that the Work
84+
or a Contribution incorporated within the Work constitutes direct
85+
or contributory patent infringement, then any patent licenses
86+
granted to You under this License for that Work shall terminate
87+
as of the date such litigation is filed.
88+
89+
4. Redistribution. You may reproduce and distribute copies of the
90+
Work or Derivative Works thereof in any medium, with or without
91+
modifications, and in Source or Object form, provided that You
92+
meet the following conditions:
93+
94+
(a) You must give any other recipients of the Work or
95+
Derivative Works a copy of this License; and
96+
97+
(b) You must cause any modified files to carry prominent notices
98+
stating that You changed the files; and
99+
100+
(c) You must retain, in the Source form of any Derivative Works
101+
that You distribute, all copyright, patent, trademark, and
102+
attribution notices from the Source form of the Work,
103+
excluding those notices that do not pertain to any part of
104+
the Derivative Works; and
105+
106+
(d) If the Work includes a "NOTICE" text file as part of its
107+
distribution, then any Derivative Works that You distribute must
108+
include a readable copy of the attribution notices contained
109+
within such NOTICE file, excluding those notices that do not
110+
pertain to any part of the Derivative Works, in at least one
111+
of the following places: within a NOTICE text file distributed
112+
as part of the Derivative Works; within the Source form or
113+
documentation, if provided along with the Derivative Works; or,
114+
within a display generated by the Derivative Works, if and
115+
wherever such third-party notices normally appear. The contents
116+
of the NOTICE file are for informational purposes only and
117+
do not modify the License. You may add Your own attribution
118+
notices within Derivative Works that You distribute, alongside
119+
or as an addendum to the NOTICE text from the Work, provided
120+
that such additional attribution notices cannot be construed
121+
as modifying the License.
122+
123+
You may add Your own copyright statement to Your modifications and
124+
may provide additional or different license terms and conditions
125+
for use, reproduction, or distribution of Your modifications, or
126+
for any such Derivative Works as a whole, provided Your use,
127+
reproduction, and distribution of the Work otherwise complies with
128+
the conditions stated in this License.
129+
130+
5. Submission of Contributions. Unless You explicitly state otherwise,
131+
any Contribution intentionally submitted for inclusion in the Work
132+
by You to the Licensor shall be under the terms and conditions of
133+
this License, without any additional terms or conditions.
134+
Notwithstanding the above, nothing herein shall supersede or modify
135+
the terms of any separate license agreement you may have executed
136+
with Licensor regarding such Contributions.
137+
138+
6. Trademarks. This License does not grant permission to use the trade
139+
names, trademarks, service marks, or product names of the Licensor,
140+
except as required for reasonable and customary use in describing the
141+
origin of the Work and reproducing the content of the NOTICE file.
142+
143+
7. Disclaimer of Warranty. Unless required by applicable law or
144+
agreed to in writing, Licensor provides the Work (and each
145+
Contributor provides its Contributions) on an "AS IS" BASIS,
146+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147+
implied, including, without limitation, any warranties or conditions
148+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149+
PARTICULAR PURPOSE. You are solely responsible for determining the
150+
appropriateness of using or redistributing the Work and assume any
151+
risks associated with Your exercise of permissions under this License.
152+
153+
8. Limitation of Liability. In no event and under no legal theory,
154+
whether in tort (including negligence), contract, or otherwise,
155+
unless required by applicable law (such as deliberate and grossly
156+
negligent acts) or agreed to in writing, shall any Contributor be
157+
liable to You for damages, including any direct, indirect, special,
158+
incidental, or consequential damages of any character arising as a
159+
result of this License or out of the use or inability to use the
160+
Work (including but not limited to damages for loss of goodwill,
161+
work stoppage, computer failure or malfunction, or any and all
162+
other commercial damages or losses), even if such Contributor
163+
has been advised of the possibility of such damages.
164+
165+
9. Accepting Warranty or Additional Liability. While redistributing
166+
the Work or Derivative Works thereof, You may choose to offer,
167+
and charge a fee for, acceptance of support, warranty, indemnity,
168+
or other liability obligations and/or rights consistent with this
169+
License. However, in accepting such obligations, You may act only
170+
on Your own behalf and on Your sole responsibility, not on behalf
171+
of any other Contributor, and only if You agree to indemnify,
172+
defend, and hold each Contributor harmless for any liability
173+
incurred by, or claims asserted against, such Contributor by reason
174+
of your accepting any such warranty or additional liability.
175+
176+
END OF TERMS AND CONDITIONS
177+
178+
APPENDIX: How to apply the Apache License to your work.
179+
180+
To apply the Apache License to your work, attach the following
181+
boilerplate notice, with the fields enclosed by brackets "[]"
182+

# Reactive Java Microservices with Spring Boot and JHipster 🤓
3+
4+
This example uses JHipster 7 to generate a reactive microservices architecture with Spring Cloud Gateway and Spring WebFlux. See [Reactive Java Microservices with Spring Boot and JHipster](https://developer.okta.com/blog/2021/01/20/reactive-java-microservices) to see how it was built.
5+
6+
**Prerequisites:** [Java 11](https://sdkman.io/sdks#java) and [Docker](https://docs.docker.com/engine/install/).
7+
8+
* [Getting Started](#getting-started)
9+
* [Links](#links)
10+
* [Help](#help)
11+
* [License](#license)
12+
13+
## Getting Started
14+
15+
To install this example, run the following commands:
16+
17+
```bash
18+
git clone https://github.com/oktadeveloper/java-microservices-examples.git
19+
cd java-microservices-examples/reactive-jhipster
20+
```
21+
22+
The JHipster Registry and Spring Cloud Config are pre-configured to use Okta. That means if you try to run them, you won't be able to login until you create an account, and an application in it.
23+
24+
Install the Okta CLI using the instructions on [cli.okta.com](https://cli.okta.com) and come back here when you're done. If you don't have an Okta developer account, run `okta register`.
25+
26+
**NOTE**: You can also use your browser and Okta's developer console to register an app. See [JHipster's security documentation](https://www.jhipster.tech/security/#okta) for those instructions.
27+
28+
From the gateway project's directory, run `okta apps create jhipster`. Accept the default redirect URIs.
29+
30+
This process does several things:
31+
32+
1. Registers an OIDC app in Okta with JHipster's configured redirect URIs.
33+
2. Creates `ROLE_ADMIN` and `ROLE_USER` groups and adds your user to both.
34+
3. Creates a `groups` claim and adds it to ID tokens.
35+
4. Creates a `.okta.env` file with the values you'll need to talk to Okta.
36+
37+
Spring Cloud Config allows you to distribute Spring's configuration between apps. Update `gateway/src/main/docker/central-server-config/localhost-config/application.yml` to use your Okta app settings. You can find the values for each property in the `.okta.env` file.
38+
39+
```yaml
40+
spring:
41+
security:
42+
oauth2:
43+
client:
44+
provider:
45+
oidc:
46+
issuer-uri: https://<your-okta-domain>/oauth2/default
47+
registration:
48+
oidc:
49+
client-id: <client-id>
50+
client-secret: <client-secret>
51+
```
52+
53+
Save your changes. These values will be distributed to the JHipster Registry, gateway, blog, and store apps. Start all the services and apps using the following commands:
54+
55+
```shell
56+
cd gateway
57+
docker-compose -f src/main/docker/keycloak.yml up -d #jhkeycloakup
58+
docker-compose -f src/main/docker/postgresql.yml up -d #jhpostgresqlup
59+
docker-compose -f src/main/docker/jhipster-registry.yml up -d #jhregistryup
60+
./gradlew
61+
```
62+
63+
Open a new terminal window, start the blog app's Neo4j database, and then the app itself.
64+
65+
```shell
66+
cd ../blog
67+
docker-compose -f src/main/docker/neo4j.yml up -d #jhneo4jup
68+
./gradlew
69+
```
70+
71+
Then, open another terminal window, start the store app's MongoDB database, and the microservice.
72+
73+
```shell
74+
cd ../store
75+
docker-compose -f src/main/docker/mongodb.yml up -d #jhmongoup
76+
./gradlew
77+
```
78+
79+
Now, open a new incognito browser window, go to `http://localhost:8080`, and sign in. Rejoice that using Okta for authentication works!
80+
81+
**TIP**: You can also run everything using Docker Compose. See the [blog post](https://developer.okta.com/blog/2021/01/20/reactive-java-microservices#run-your-microservices-stack-with-docker-compose) for how to do that.
