java8升級(jí)java21方法步驟(完整pom文件升級(jí)及代碼修改)
更新時(shí)間：2024年11月07日 10:21:39 作者：JDHWA
在從Java?8升級(jí)至Java?211的過程中,需要對(duì)多個(gè)POM文件進(jìn)行升級(jí),涉及parent、web、service等模塊,文中通過代碼介紹的非常詳細(xì),對(duì)大家學(xué)習(xí)或者使用java具有一定的參考借鑒價(jià)值,需要的朋友可以參考下
java8升級(jí)java21
1、pom文件升級(jí)

4、 升級(jí)修改配置
XxlJobConfig
appName字段名稱更新
XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor(); //xxlJobSpringExecutor.setAppName(appName); xxlJobSpringExecutor.setAppname(appName);
DataSourceConfig
分頁及樂觀鎖插件配置
@Configuration
@EnableTransactionManagement
@MapperScan("com.test.mapper")
public class DataSourceConfig {
/**
* 分頁及樂觀鎖 插件
*
* @return the page and optimistic locker interceptor
*/
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor(){
MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
mybatisPlusInterceptor.addInnerInterceptor(
new PaginationInnerInterceptor(DbType.MYSQL));
mybatisPlusInterceptor.addInnerInterceptor(
new OptimisticLockerInnerInterceptor());
return mybatisPlusInterceptor;
}
}
SecurityConfig
原配置ResourceServerConfigurerAdapter已過時(shí)
@EnableResourceServer
@EnableOAuth2Client
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Configuration
@Slf4j
public class SecurityConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
// @formatter:off
http.authorizeRequests()
.antMatchers(
"/url",
"/url"
).permitAll()
.anyRequest().authenticated();
// @formatter:on
}
}
新配置
@EnableWebSecurity
@Configuration
@Slf4j
@EnableConfigurationProperties({ResourceServerProperties.class})
public class SecurityConfig {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
// @formatter:off
http.authorizeHttpRequests((authz) -> authz
.requestMatchers(
"url",
"url")
.authenticated()).httpBasic(withDefaults());
return http.build();
// @formatter:on
}
}
5、 代碼修改
javax替換為jakarta
import javax.validation.constraints.NotBlank; import jakarta.validation.constraints.NotBlank; import javax.validation.constraints.NotEmpty; import jakarta.validation.constraints.NotEmpty; import javax.servlet.http.HttpServletRequest; import jakarta.servlet.http.HttpServletRequest; import javax.annotation.PostConstruct; import jakarta.annotation.PostConstruct; import javax.servlet.http.HttpServletResponse; import jakarta.servlet.http.HttpServletResponse; import javax.validation.constraints.FutureOrPresent; import jakarta.validation.constraints.FutureOrPresent; import javax.validation.ConstraintViolation; import jakarta.validation.ConstraintViolation; import javax.validation.Validator; import jakarta.validation.Validator; import javax.servlet.ServletOutputStream; import jakarta.servlet.ServletOutputStream;
mybatiesplus 數(shù)據(jù)庫實(shí)體注解內(nèi)容替換
@TableId(value = "id", type = IdType.ID_WORKER) @TableId(value = "id", type = IdType.ASSIGN_ID) @TableField(value = "start_time", strategy = FieldStrategy.IGNORED) @TableField(value = "start_time", updateStrategy = FieldStrategy.IGNORED)
XXLJob
原代碼
@JobHandler(value = "Job")
@Component
@Slf4j
public class Job extends IJobHandler {
@Override
public ReturnT<String> execute(String param) throws Exception {
ShardingUtil.ShardingVO shardingVo = ShardingUtil.getShardingVo();
int index = shardingVo.getIndex();
int total = shardingVo.getTotal();
XxlJobHelper.log("log", index);
service.execute(param);
return ReturnT.SUCCESS;
}
}
新代碼
@Component
@Slf4j
public class Job extends IJobHandler {
@Override
@XxlJob("Job")
public void execute() throws Exception {
int index = XxlJobHelper.getShardIndex();
int total = XxlJobHelper.getShardTotal();
XxlJobHelper.log("log", index);
String param = XxlJobHelper.getJobParam();
service.execute(param);
}
}總結(jié)
