org.springframework.boot
spring-boot-starter-parent
1.5.10.RELEASE
org.springframework.boot
spring-boot-starter-parent
2.0.7.RELEASE
Spring Data的一些方法进行了重命名:
创新互联建站坚持“要么做到,要么别承诺”的工作理念,服务领域包括:网站建设、成都网站建设、企业官网、英文网站、手机端网站、网站推广等服务,满足客户于互联网时代的舞阳网站设计、移动媒体设计的需求,帮助企业找到有效的互联网解决方案。努力成为您成熟可靠的网络建设合作伙伴!
在升级时,可以在pom中增加spring-boot-properties-migrator,这样在启动时会提示需要更改的配置:
org.springframework.boot
spring-boot-properties-migrator
runtime
其中改动较大的是security(The security auto-configuration is no longer customizable,A global security auto-configuration is now provided)、management、banner、server等。
security开头的配置及management.security均已过期,如以下的配置不再支持,需要调整到代码中:
security:
ignored: /api-docs,/swagger-resources/**,/swagger-ui.html**,/webjars/**
management:
security:
enabled: false
port: 8090
修改为:
management:
server:
port: 8090
datasource:
initialize: false
修改为:
datasource:
initialization-mode: never
如使用PostgreSQL,可能会报错:Method org.postgresql.jdbc.PgConnection.createClob() is not yet implemented hibernate,需修改配置:
jpa:
database-platform: org.hibernate.dialect.PostgreSQLDialect
properties:
hibernate:
default_schema: test
jdbc:
lob:
non_contextual_creation: true
更多需要调整的参数请看文末参考文档。
WebSecurityConfigurerAdapter
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/api-docs", "/swagger-resources/**", "/swagger-ui.html**", "/webjars/**");
}
如在代码中注入了AuthenticationManager,
@Autowired
private AuthenticationManager authenticationManager;
在启动时会报错:Field authenticationManager required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.请在WebSecurityConfigurerAdapter中增加以下代码:
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
Old property | New property |
---|---|
endpoints.id.* | management.endpoint.id.* |
endpoints.cors.* | management.endpoints.web.cors.* |
endpoints.jmx.* | management.endpoints.jmx.* |
management.address | management.server.address |
management.context-path | management.server.servlet.context-path |
management.ssl.* | management.server.ssl.* |
management.port | management.server.port |
management.endpoints.web.base-path的默认值为/actuator,即Actuator访问路径前部增加了actuator([/actuator/health],[/actuator/info]),这可以在启动日志中看到。
因management.security不再支持,权限配置需添加到WebSecurityConfigurerAdapter中:
.authorizeRequests()
.requestMatchers(EndpointRequest.to("health", "info")).permitAll()
Endpoint | Changes |
---|---|
/actuator | No longer available. There is, however, a mapping available at the root of management.endpoints.web.base-path that provides links to all the exposed endpoints. |
/auditevents | The after parameter is no longer required |
/autoconfig | Renamed to /conditions |
/docs | No longer available (the API documentation is part of the published documentation now) |
/health | Rather than relying on the sensitive flag to figure out if the health endpoint had to show full details or not, there is now a management.endpoint.health.show-details option: never, always, when-authorized. By default, /actuator/health is exposed and details are not shown. |
/trace | Renamed to /httptrace |
可以在代码中直接使用Binder API从配置文件中读取内容:
public class Person implements EnvironmentAware {
private Environment environment;
@Override
public void setEnvironment(Environment environment) {
this.environment = environment;
}
public void bind() {
List people = Binder.get(environment)
.bind("my.property", Bindable.listOf(PersonName.class))
.orElseThrow(IllegalStateException::new);
}
}
YAML配置
my:
property:
- first-name: Jane
last-name: Doe
- first-name: John
last-name: Doe
新增spring.data.web配置来设置分页和排序:
# DATA WEB (SpringDataWebProperties)
spring.data.web.pageable.default-page-size=20 # Default page size.
spring.data.web.pageable.max-page-size=2000 # Maximum page size to be accepted.
spring.data.web.pageable.one-indexed-parameters=false # Whether to expose and assume 1-based page number indexes.
spring.data.web.pageable.page-parameter=page # Page index parameter name.
spring.data.web.pageable.prefix= # General prefix to be prepended to the page number and page size parameters.
spring.data.web.pageable.qualifier-delimiter=_ # Delimiter to be used between the qualifier and the actual page number and size properties.
spring.data.web.pageable.size-parameter=size # Page size parameter name.
spring.data.web.sort.sort-parameter=sort # Sort parameter name.
# JDBC (JdbcProperties)
spring.jdbc.template.fetch-size=-1 # Number of rows that should be fetched from the database when more rows are needed.
spring.jdbc.template.max-rows=-1 # Maximum number of rows.
spring.jdbc.template.query-timeout= # Query timeout. Default is to use the JDBC driver's default configuration. If a duration suffix is not specified, seconds will be used.

2.9.2
io.springfox
springfox-swagger-ui
2.9.2
Swagger 2.9版本,增加了对@ApiParam属性example的处理,在Swagger UI和文档中会显示,因此要注意设置合适的example值:
@ApiOperation(value = "Delete airline by id")
@GetMapping("/airlines/delete/{airlineId}")
public void deleteAirline(@ApiParam(required = true, example = "123") @PathVariable Long airlineId)
否则你会看到Warn日志:
AbstractSerializableParameter
@JsonProperty("x-example")
public Object getExample() {
if (example == null) {
return null;
}
try {
if (BaseIntegerProperty.TYPE.equals(type)) {
return Long.valueOf(example);
} else if (DecimalProperty.TYPE.equals(type)) {
return Double.valueOf(example);
} else if (BooleanProperty.TYPE.equals(type)) {
if ("true".equalsIgnoreCase(example) || "false".equalsIgnoreCase(defaultValue)) {
return Boolean.valueOf(example);
}
}
} catch (NumberFormatException e) {
LOGGER.warn(String.format("Illegal DefaultValue %s for parameter type %s", defaultValue, type), e);
}
return example;
}
另外Swagger 2.9.2会为org.springframework.data.domain.Pageable自动增加@ApiImplicitParams。
