这有什么不对？我无法访问home.jsp.我实际上是在春季3.0观看教程,我已经完成了视频中的显示.谁能在这里指出我的错误？

我有这个hibernate dao,它在我的本地机器上测试时工作正常.但对于某些事务,它会抛出IllegalStateException.我相信这是因为多个用户同时打.(我可能错了).

UpdatePaymentDao

@Repository公共类UpdatePaymentImpl实现UpdatePayment {

@Repository
public class UpdatePaymentImpl implements UpdatePayment {


    @Autowired
    SessionFactory sessionFactory;
    Session session;
    Transaction trans;

    private static final long LIMIT = 100000000000L;
    private static final long LIMIT2 = 10000000000L;
    private static long last = 0;


    public static long getUniqueID() {
        // 10 digits.
        long id = (System.currentTimeMillis() % LIMIT) + LIMIT2;
        System.out.println("id"+id);
        System.out.println("system time"+System.currentTimeMillis());
        System.out.println("milssiiiiii=============="
                + System.currentTimeMillis());
        if (id <= last) {
            id = (last + 1) % LIMIT;
        }
        return last = id;
    }

    public …

我有一张桌子。

如您所见， created_date 列是时间戳字段。现在选择我只想考虑日期值。例如，如果我想从今天开始选择行，我想做以下事情：-

select * from audit_logs where created_date = '2018-11-28';

上面的查询返回 null。可以这样选择吗？

我正在尝试使用 postgres 数据库设置 Spring Boot 项目。我的实体是：-

用户

@Entity
public class User implements UserDetails {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="id", nullable = false, updatable = false)
    private Long id;
    private String username;
    private String password;
    private String firstName;
    private String lastName;

    @Column(name="email", nullable = false, updatable = false)
    private String email;
    private String phone;
    private boolean enabled=true;


    @OneToMany(mappedBy = "user", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @JsonIgnore
    private Set<UserRole> userRoles = new HashSet<>();

    public Long getId() {
        return id;
    }
    public void setId(Long …

我在做简单的测试。

@Test
    public void whenFilterEmployees_thenGetFilteredEmployees(){
        Integer[] empIds = {1,2,3};
        List<Optional<Employee>> employees = Stream.of(empIds)
                .map(employeeRepository::findById)
                .collect(Collectors.toList());

        List<Employee> employeeList = employees
                .stream().filter(Optional::isPresent)
                .map(Optional::get)
                .filter(e->e !=null)
                .filter(e->e.getSalary()>200000)
                .collect(Collectors.toList());

        assertEquals(Arrays.asList(arrayOfEmps[2]), employeeList);


    }

我的员工表包含数据：

1   Jeff Bezos  100000
2   Bill Gates  200000
3   Mark Zuckerberg 300000

当前测试成功运行。

如您所见，我准备了两个员工列表，即员工和员工列表

我这样做是因为findById方法返回 Optional。我如何使用流 api 以便我可以简单地获取员工列表

List<Employee> employeeList= ....

我正在尝试使用3.0.7.RELEASE基于spring mvc java的配置的thymeleaf .

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.sagar")
public class MvcConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware{

    @Autowired
    RoleToUserProfileConverter roleToUserProfileConverter;

    private ApplicationContext applicationContext;

    public void setApplicationContext(ApplicationContext applicationContext) {
        this.applicationContext = applicationContext;
    }

    @Bean
    public ViewResolver viewResolver() {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine());
        resolver.setCharacterEncoding("UTF-8");
        return resolver;
    }

    @Bean
    public TemplateEngine templateEngine() {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setEnableSpringELCompiler(true);
        engine.setTemplateResolver(templateResolver());
        return engine;
    }

    private ITemplateResolver templateResolver() {
        SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setApplicationContext(applicationContext);
        resolver.setPrefix("/WEB-INF/templates/");
        resolver.setTemplateMode(TemplateMode.HTML);
        return resolver;
    }

我正在尝试打包我的spring boot应用程序，以便可以将其部署在tomcat服务器上。观看完youtube视频后，我扩展了SpringBootServletInitializer类并进行了一些更改。

 @ComponentScan("com.infodev.loksewa")
    @SpringBootApplication
    public class LoksewaApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(LoksewaApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(LoksewaApplication.class);
    }
}

每当我在html文件上更改某些内容时,我必须重新启动整个项目.我试过了:-

- >编辑配置 - >服务器并更改帧检测以更新资源.

在我的服务器选项卡上,还有关于帧检测的更新资源.但仍然无法更新我的html文件,我必须重新启动服务器以反映我的更改.

Intellij Idea版本是2017年.

我必须上课

public class Consumer{


private String name;
private int salary;


public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getSalary() {
    return salary;
}

public void setSalary(int salary) {
    this.salary = salary;
}
}

接下来

public class Donor {

private String name;
private int amount;
private String location;



public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getAmount() {
    return amount;
} …
