java 工程搜索字段_java – 在spring boot中检索特定字段

经过更多的实验,我找到了在Controller中使用Squiggly库和spring boot以及spring web注释的最简单方法.您应该做的唯一一件事是添加配置类,如下所示：

@Configuration

@ConditionalOnClass(ObjectMapper.class)

public class SquigglyAutoconfigure {

@Bean

public FilterRegistrationBean squigglyRequestFilter(ObjectMapper objectMapper) {

Squiggly.init(objectMapper, new RequestSquigglyContextProvider());

FilterRegistrationBean filter = new FilterRegistrationBean<>();

filter.setFilter(new SquigglyRequestFilter());

filter.setOrder(1);

return filter;

}

}

然后当您将查询参数“fields”添加到控制器内的任何端点时：

@RequestParam(name = "fields", required = false) String fields

您将过滤回复.例如,使用这种响应体：

{

"id": "ISSUE-1",

"issueSummary": "Dragons Need Fed",

"issueDetails": "I need my dragons fed pronto.",

"reporter": {

"firstName": "Daenerys",

"lastName": "Targaryen"

}

}

当您使用fields = id,reporter.firstName发出请求时,您将获得：

{

"id": "ISSUE-1",

"reporter": {

"firstName": "Daenerys"

}

}
