I realised reading a file into bytes-array with next writing this array to file in another directory by the following approach:
try(FileInputStream fis = new FileInputStream(attachFile)){ ZipOutputStream zipOutputStream = null; byte[] bytes = new byte[BUFFER_SIZE]; int length; while ((length = fis.read(bytes)) >= 0) {      zipOutputStream.write(bytes, 0, length);   } }

And this code done well - in target directory appear new file with the relevant content (for example: "abcd").

Further I tried to improve my approach through ApacheCommons abilities.

try(FileInputStream fis = new FileInputStream(attachFile)){  ZipOutputStream zipOutputStream = null;  byte[] bytes = new byte[BUFFER_SIZE];  IOUtils.read(fis, bytes);  IOUtils.write(bytes, zipOutputStream); }

But this approach entails the problem: in target directory the new file appeals, but this written content is irrelevant. Besides the written text (for example: "abcd") it contains some unreadable unencoded symbols, and I see the warning about problem with encoding.

I suppose this problem is related to the fact, that some excess bytes read and/or write to OutpumStream. And this problem (probably) arise due to the fact I don't restrict read and write-operations, applying IOUtils (second approach).

And in first approach I restrict the write of byte-array in OutputStream by size of length-variable:

while ((length = fis.read(bytes)) >= 0)
If problem in that I must have a way to restrict the write by tools of AppacheCommons.
But I don't see any way to do so in IOUtils-methods.

I'm trying to test service-class of reactive mongoDB application, created on SpringBoot.

I don't use embedded mongodb! I'm only trying to mock repository

This is reactive mongo repository:
package com.spb.budget_server.repository; public interface EntryRepository extends ReactiveMongoRepository<Entry, String> {  }

Repository, which should use it:
package com.spb.budget_server.repository.impl; @AllArgsConstructor @Repository public class EntryRepositoryImpl {    private EntryRepository entryRepository;    // }

And test class:
@ExtendWith(SpringExtension.class) @SpringBootTest(classes = {EntryRepositoryImpl.class, EntryRepository.class})   public class EntryServiceTest {    @Autowired    private EntryRepositoryImpl entryRepositoryImpl;       //  }

Main configuration:

@Configuration @EnableReactiveMongoRepositories() public class MongoConfig extends AbstractReactiveMongoConfiguration {  // some db-settings }

May be It doesn't matter is that case, but test-configurations is:
@TestConfiguration public class TestConfig {    @Bean    public EntryRepositoryImpl mockEntryRepositoryImpl() {         return Mockito.mock(EntryRepositoryImpl.class);      } }

And, after running test, I receive the following exception:

Error creating bean with name 'entryRepositoryImpl':
caused by:
NoSuchBeanDefinitionException: No qualifying bean of type 'com.spb.budget_server.repository.EntryRepository' available: expected at least 1 bean which qualifies as autowire candidate

What am I doing wrong?

  Hello!

  I have 2 entities:

  @Entity @Inheritance(strategy=InheritanceType.SINGLE_TABLE)  @Table(appliesTo = "A", indexes = {@Index(name = "a_uuid_idx", columnNames = {"uuid"})})  public class A {   @Id   @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "EntityID")   @Access(AccessType.PROPERTY)   private Integer id; }

@Entity  @DiscriminatorValue("local.stored")  public class B extends A {   private String name; }

  And data from B successfully persists in table A. So, one table for 2 entities - A and B.
 

  I created third entity - C.
    @Entity    @Table (name="C")   public class C extends B {   private String lastname; }

  I want data from C to persisted in separate table - C.  
  So, finally -  one table A for A/B entities,  and one more table for C.
  In this case 2 strategies are mixed: SINGLE_TABLE  and  TABLE_PER_CLASS

  For this purpose i applied to B annotation @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)

  @Entity @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)  @DiscriminatorValue("local.stored")  public class B extends A {   private String name; }

 But without success - data from C persisted in single table A.   So SINGLE_TABLE  is working only

 

   Thank you! It s a foolishness, but I mixed up Apache Maven and Apache Tomcat

What is the valid tomcat directory in Windows?

I tried to configure apache-maven in Idea in C:\Program Files

But receive: "The selected directory is not a valid tomcat home"

WildFly 14.0.1:

I enter "http://127.0.0.1:8080/" in browser succesfully.

But when when I enter "http://127.0.0.1:9990/console", I receive "Cannot access to site".

Trying to run WildFly I receive following exceptions:

NullPointedException   at _redirected._RedirectedUtils.loadProvider(_RedirectedUtils.java94)

Also I see, that it does not have data-directory and logs.

jBoss is installed, but i cant run it too due to the above reason.

jdk-8 is installed in the same root-directory: C:\Program Files

  I'm still "anchored"....

 Hello!

 I have the following maven-dependency:

<postgresql.version>42.2.11</postgresql.version>    <dependency>        <groupId>org.postgresql</groupId>        <artifactId>postgresql</artifactId>        <version>${postgresql.version}</version>    </dependency>

 Project-properties:

<java.version>11.0.6</java.version>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <spring.version>5.2.4.RELEASE</spring.version>        <spring-data-jpa.version>2.2.5.RELEASE</spring-data-jpa.version>        <tomcat.version>9.0.27</tomcat.version>

And try to use it by spring-xml-configuration:

<bean id="dataSource"      class="org.apache.tomcat.jdbc.pool.DataSource"      p:driverClassName="org.postgresql.Driver"      p:url="${database.url}"      p:username="${database.user}"      p:password="${database.password}"/> But during deployment I receive: [code=java] java.lang.ClassNotFoundException: org.postgresql.Driver at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:471) at java.base/java.lang.ClassLoader.loadClass .....

SDK is 11.0.6.

I tried:
1. Rebuild project.

2. Invalidate Caches/Restart

3. Maven Clean/Install.  But Install failed by the reason of:

 
     Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project user_service: Fatal error compiling


Help me, please!!!  I almost a day battle with this problem

    I have found the solution:

   I add separate controller:

  @Controller @RequestMapping( value = TestRegistrationController.TEST_CONFIRM_REGISTRATION_URL ) public class TestRegistrationController {    public static final String TEST_CONFIRM_REGISTRATION_URL = "/testConfirmRegistration";    public static final String TEST_FORWARD_DENIED_URL = "forward:/denied/access_denied.html";    @Autowired    TokenService tokenService;    @GetMapping    public String confirmRegistration(@RequestParam("token") String token) {        String responce;        Token verificationToken = tokenService.getToken(token);        if (verificationToken == null || verificationToken.getExpiryDateTime().isBefore(LocalDateTime.now())) {            responce = TEST_FORWARD_DENIED_URL;        }        else {            tokenService.delete(token);            responce = "forward:/";        }        return responce;    } }

And conroller for the root-mappring:

@Controller @RequestMapping("/") public class RootController {    @GetMapping    public String showPage() {        return "redirect:/approved/access_approved.html";    } }

new spring-config:

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"          p:prefix="/WEB-INF/"          p:suffix=".html"/>    <mvc:resources mapping="/**" location="/WEB-INF/"/>

Besides I remain @RestController.  

So this solution cost for my project architecture-sophistication...

 Have somebody any idea?

Hibernate properties are represent as:

<map>            <entry key="#{T(org.hibernate.cfg.AvailableSettings).FORMAT_SQL}"       value="${hibernate.format_sql}"/>            <entry key="#{T(org.hibernate.cfg.AvailableSettings).USE_SQL_COMMENTS}"                   value="${hibernate.use_sql_comments}"/>            <entry key="#{T(org.hibernate.cfg.AvailableSettings).JPA_PROXY_COMPLIANCE}"       value="false"/>            <entry key="#{T(org.hibernate.cfg.AvailableSettings).HBM2DDL_AUTO}"       value="update"/>        </map>


Postgres-driver is 42.2.10
Spring Data JPA

In general hybernate working well: it provides all CRUD-operations.

But if try to update my Entity (for example, by adding new field), assigned table in database is not changing.

 
    I add to spring-mvc.xml the following:

 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"          p:suffix=".html"/>

   and controller:

@Controller @RequestMapping ( "/" ) public class HtmlTestingController {    @GetMapping    public String showPage() {        return "redirect:access_approved";    } }

directory: test/webapp/access_approved.html.


It redirects me on http://localhost:8080/test/access_approved.    But with the same 404-error.

I tried "forward:access_approved"
But it forwards me on http://localhost:8080/test/
