I have a spring boot, java 8 API that I wanted to add a React front end to to make API operations easier to navigate and use. I used JHipster generator to generate a React app. Then I just took the web portion and dropped into my app, however whenever I run the Spring Boot application and try to navigate to port :8080 it, I get the following page:
And the following error in the console:

How do I get spring boot to serve up the index.html file when navigating to localhost:8080? I know I'm going to have to override some default spring boot configurations to get this to work but I'm not clear on what configurations.
I can provide details of any more files upon request, just didn't want to overload the post with unnecessary info.
Request mapping for your application's entry point, read the file, and return the content. In my case, the React code is stored at /tmp/build/index.html. Simplified and ignoring errors, it might look something like this:
#RequestMapping(
value = "",
method = RequestMethod.GET)
public ResponseEntity<String> getIndexContent() {
final File file = new File("/tmp/build/index.html");
final String content =
FileUtils.readFileToString(
file,
StandardCharsets.UTF_8);
return ResponseEntity
.ok()
.contentType(MediaType.TEXT_HTML)
.body(content);
}
Spring-boot auto-configures some paths by default as static resource locations: /static, /public or /resources. See the Official Spring Docs
So if you can move your index.html and dependent assets into the static resource paths, Spring Boot should serve them as-is.
Alternatively, as those same docs say, you could add new paths as a static locations by setting the spring.resources.static-locations property.
A nice thing to do would be to build your React application, bundling the resources, and copying the bundled assets + index.html to the Spring project's static location.
You haven't mentioned anything about your build setup, if you're using the Gradle Node Plugin with Webpack, then this shouldn't be hard. This blog post shows how you'd do that (however, not using multiple modules)

I have a controller with an endpoint that provide a flux like this reported below.
When the app is deployed to kubernetes, methods doOnCancel and doOnTerminate are not invoked.
Locally instead, it works like a charm (when the tab of the browser is closed as instance).
#Slf4j
#RestController
public class TestController {
...
#GetMapping(value = "/test", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
public Flux<String> testStream() {
log.info("Requested test streaming");
return mySink.asFlux()
.startWith("INIT TEST")
.doOnCancel(() -> log.info("On cancel"))
.doOnTerminate(() -> log.info("On terminate"));
}
...
}

Has anyone encountred the same problem?
Any idea about that?
I have a Java Spring Boot application (Java 8 JDK) that makes calls to a REST service. For the delete resource case, I need to specify the path as follows: /api/v4/projects/<URL encoded project path>, where the project path is typically represented as a parent "group" followed by the project name. For example: my-group/my-project. So, when I invoke the delete case, the example path needs to be my-group%2Fmy-project.
I am using java.net.URLEncoder.encode(value, StandardCharsets.UTF_8.toString()) to do the encoding and it converts the example path to what it needs to be (the group is test and the project is test-cold-storage):
https://<removed>/api/v4/projects/test%2Ftest-cold-storage
When I invoke the call, however, it fails. I have an interceptor that prints out the details of the request being made. It's showing something unexpected.
2022-07-18 15:49:18.030 INFO 21888 --- [ main] c.b.d.c.c.CustomRequestInterceptor : Request:
2022-07-18 15:49:18.030 INFO 21888 --- [ main] c.b.d.c.c.CustomRequestInterceptor : URI: https://<removed>/api/v4/projects/test%252Ftest-cold-storage
2022-07-18 15:49:18.030 INFO 21888 --- [ main] c.b.d.c.c.CustomRequestInterceptor : Method: DELETE
It looks like it's being encoded again (maybe?). 0x25 = '%' and 0x2F = '/'. If I do it without encoding the group/path, no encoding occurs and it fails again.
2022-07-19 07:47:02.146 INFO 5200 --- [ main] c.b.d.c.c.CustomRequestInterceptor : Request:
2022-07-19 07:47:02.147 INFO 5200 --- [ main] c.b.d.c.c.CustomRequestInterceptor : URI: https://<removed>/api/v4/projects/test/test-cold-storage
2022-07-19 07:47:02.147 INFO 5200 --- [ main] c.b.d.c.c.CustomRequestInterceptor : Method: DELETE
Has anyone else run into this? Is there some setting in the configuration of the RestTemplate object that affects this?
UPDATE
I have managed to trace execution in the debugger and found that it is encoding the URL. This is happening in org.springframework.web.util.DefaultUriBuilderFactory.createURI().
I don't know if this information is helpful.
Figured it out. I needed to pass the project path (i.e. test/test-cold-storage) as a URI variable instead of tacking it on the end of the URL. The endpoint URL need to change as follows:
String endpointURL = baseURL + GITLAB_REST_API + "projects/{path}";
and the delete call changed to add URI variable (projectPath):
template.delete(endpointURL, projectPath);, where in this example projectPath is test/test-cold-storage.
I am switching from python pandas to Java Spark for data analytics and new to it. In my project I'm not using hadoop, just fetching data from mysql db.
The code is like this:
List<QtStkDailyRehabilitation> qtStkDailyRehabilitations = qtStkDailyRehabilitationSelfMapper.getStockDailyKData(stockCode);
SparkSession spark = SparkSession.builder().appName("sparkTest").config("spark.master","local")
.getOrCreate();
StructField field1 = DataTypes.createStructField("date", DataTypes.DateType, false);
StructField field2 = DataTypes.createStructField("close", DataTypes.FloatType, false);
StructType stockInfo = DataTypes.createStructType(Lists.newArrayList(field1, field2));
...
So I didn't install a hadoop on my computer. But I found when I create a SparkSession, it takes a long time - around 20 seconds, and it comes out with a warning.
The log shows below:
2020-05-26 18:45:02.507 DEBUG 15880 --- [nio-8031-exec-1] c.e.d.q.d.Q.getStockDailyKData : ==> Preparing: SELECT * FROM qt_stk_daily_rehabilitation WHERE (stock_code='002241') ORDER BY trade_date DESC

As you can see. Running Spark version 2.4.3 shows 10s after sql returns results, and then after 9s it prints a warning about hadoop.
Following codes works ok and I can use DataFrame to calculate, but every time I run into this session create code it will take 20s. I guess it tries to access hadoop server which I don't have one. Is it normal and how to make it faster? Or can I disable hadoop for now just to enjoy it's MLlib features?
Thanks.

I don't understand, how can the same tests pass at first, but fail when I move them to docker container?
It looks like the test container with the database has started successfully, so no issue there, you're getting an empty database.
Then you try running the flyway and this fails.
Flyway in spring boot works during the initialization of the spring application context,
so the actual migration runs while the application context gets initialized, so the migration failure looks like a spring failure.
The reason, however, is logged: the migration file has an invalid content:
Migration V1__initial_user.sql failed

This GENERATED BY is unsupported.
Why? Probably your docker image includes the version of RDBMS that doesn't support this syntax. So it differs from the DB that you use in a local environment without docker.
In any case it's not about docker, spring or flyway but about the DB and the migration code.
In terms of resolution, I suggest running the docker image of the DB directly (without java, testcontainers and flyway).
When it runs, just run this migration "manually" in pgadmin or something. You're expected to see the same error.
Thank you #M. Deinum and Mark Bramnik!
I found out that the issue is with Postgres version. For some reason by default docker image is created with old version 9.6.12, but sql script GENERATED BY DEFAULT was added to Postgres with version 10.
Solution 1 (Update the sql script to older version):
CREATE TABLE revinfo
(
rev INTEGER PRIMARY KEY NOT NULL,
revtstmp BIGINT
);
Solution 2:
Changed docker image version to 11.2 by creating CustomPostgreSQLContainer file in the project.
import org.testcontainers.containers.PostgreSQLContainer;
public class CustomPostgreSQLContainer extends PostgreSQLContainer<CustomPostgreSQLContainer> {
private static final String IMAGE_VERSION = "postgres:11.2";
private static CustomPostgreSQLContainer container;
CustomPostgreSQLContainer() {
super(IMAGE_VERSION);
}
public static CustomPostgreSQLContainer getInstance() {
if (container == null) {
container = new CustomPostgreSQLContainer();
}
return container;
}
#Override
public void start() {
super.start();
System.setProperty("spring.datasource.url", container.getJdbcUrl());
System.setProperty("spring.datasource.username", container.getUsername());
System.setProperty("spring.datasource.password", container.getPassword());
}
#Override
public void stop() {
//do nothing, JVM handles shut down
}
}
And updating BaseIntTest file:
#Testcontainers
#SpringBootTest
public class BaseIntTest {
#Container
private static final PostgreSQLContainer<?> container = CustomPostgreSQLContainer.getInstance();
And last removing two lines from test application.properties file:
spring.datasource.driver-class-name=org.testcontainers.jdbc.ContainerDatabaseDriver
spring.datasource.url=jdbc:tc:postgresql://localhost:5433/test
In my case I added in my application.properties file
spring.flyway.baselineOnMigrate = true
and I had also to start from version 1.1 instead of 1 otherwise flyway throws an error (flyway 8.0.5)
The problem in my case was because of using spring.datasource.url=jdbc:postgres://localhost:5432/todoListDb
instead of
spring.datasource.url=jdbc:postgresql://localhost:5432/todoListDb
(postgres instead of PostgreSQL) in my application.properties file
So try to use the right URL for your database and verify if there is a typo in your url
One reason for this issue was missing docker DB version: <embedded-database-spring-test.version>2.0.1</embedded-database-spring-test.version>
By adding this specific version, it worked for me.
As mentioned GENERATED BY DEFAUL needs a newer version of postgres image. In your case the postgres image defaults to 9.6.12.
Simple solution is to just update the datasource url in application.properties and point to a newer postgres image there.
spring.datasource.url=jdbc:tc:postgresql:11.2://localhost:5433/test
I'm new to spring framework and REST, and now trying to migrate REST from jersey to spring boot 2.1
The controller works fine with jax-rs, however, I don't want to use jax-rs in spring boot. So, I tried spring Mvc and I get 'resource not found' error. Please I'd really appreciate any help.
I tried this
#GetMapping(value ="/generic/download_file/{path:[^\\.+]*}", consumes ="application/vnd.X-FileContent")
public ResponseEntity<?> downloadFile(#PathVariable("path") String filePath){
String actualFilePath = "";
try {
actualFilePath = filePath.replaceAll("\\/", "\\\\");
File file = new File(actualFilePath);
if (file.exists()) {
return ResponseEntity.ok().header("Content-Disposition", "attachment; filename=\"" + file.getName() + "\"").body(file);
} else {
return errorHandling.errorResponseFactory("1.0.0", Thread.currentThread().getStackTrace()[1], "",
RecommendedSolution.UseValidDirectoryPath, "File not exist.");
}
} catch (Exception ex) {
ActionLog.writeLog("program_library_v510", "1.0.0", "Exception occur during gettig generic package file",
ActionLogType.DebugLog);
ActionLog.writeLog("program_library_v510", "1.0.0", "Exception occur during getting generic package file",
ActionLogType.ErrorLog);
return errorHandling.errorResponseFactory("1.0.0", Thread.currentThread().getStackTrace()[1], "",
RecommendedSolution.UnexpectedErrorMsg, "");
}
}

I suspect two things here. Let me clarify this.
What is the API url you are calling?
/generic/download_file/{path:[^\\.+]*} or /packages/download_file/D:/xfolder/test.txt
both are looks different. Please see generic and packages
The better way to pass filenames in URL is using #RequestParam instead of #PathVariable
#GetMapping(value ="/generic/download_file/", consumes ="application/vnd.X-FileContent")
public ResponseEntity downloadFile(#RequestParam("path") String filePath){
