摘要：如果是其它方式引發(fā)的錯(cuò)誤，此處的解決方法不可用。最與該錯(cuò)誤重要便是前兩個(gè)。仔細(xì)檢查發(fā)現(xiàn)，在接口中將參數(shù)轉(zhuǎn)化為一個(gè)對(duì)象，但沒有指出該對(duì)象就是錯(cuò)誤代碼根據(jù)查詢條件查詢登錄注冊(cè)訪問(wèn)統(tǒng)計(jì)數(shù)據(jù)解決辦法接口中添加相應(yīng)的注解。

通篇錯(cuò)誤最明顯的兩個(gè)地方：

org.jboss.resteasy.spi.InternalServerErrorException: Bad arguments passed to org.jboss.resteasy.spi.metadata.ResourceMethod@6b9e0ff4 ( cn.company.goods.pojos.PullOffShelves cn.company.goods.pojos.PullOffShelves@2e1cb83d和Caused by: java.lang.IllegalArgumentException: object is not an instance of declaring class。

錯(cuò)誤原因

在dubbox的service（itemServiceImpl）中實(shí)現(xiàn)了兩個(gè)接口（itemervice,itemPullOffShelfService）,dubbox暴露給zk的服務(wù)（dubbo:service）有兩個(gè)，但是實(shí)現(xiàn)的bean有一個(gè)（ref），zk雖然注冊(cè)了服務(wù)，但是rest（暫且當(dāng)作消費(fèi)方）調(diào)用接口的時(shí)候，不知道調(diào)用的是哪一個(gè)資源接口。

如果是其它方式引發(fā)的錯(cuò)誤，此處的解決方法不可用。

解決方法

將兩個(gè)接口合并到同一個(gè)接口或者分別實(shí)現(xiàn)兩個(gè)接口。問(wèn)題即可解決。

錯(cuò)誤原因

這是由于在接口實(shí)現(xiàn)中沒有添加相應(yīng)的注解：@QueryParam,@BeanParam,@Component,@Consumes,@Produces等注解。最與該錯(cuò)誤重要便是前兩個(gè)。

我的錯(cuò)誤指出來(lái)了，是不能找到消息體類型，這說(shuō)明傳入的參數(shù)出錯(cuò)，或者接口獲取參數(shù)出錯(cuò)。仔細(xì)檢查發(fā)現(xiàn)，在接口中將request參數(shù)轉(zhuǎn)化為一個(gè)對(duì)象，但沒有指出該對(duì)象就是@BeanParam.

錯(cuò)誤代碼：

@Component("loginRegisterService")
@Path("statistics")
@Produces({ContentType.APPLICATION_JSON_UTF_8})
public class LoginRegisterServiceImpl implements LoginRegisterService {
    Log logger = LogFactory.getLog(LoginRegisterServiceImpl.class);

    @Resource
    private LoginRegisterStRepo login;
    /**
     * 根據(jù)查詢條件查詢登錄注冊(cè)訪問(wèn)統(tǒng)計(jì)數(shù)據(jù)
     *
     * @param search
     * @return
     */
    @Override
    @GET
    @Path("login_reg")
    public List getLoginRegSt(final BaseSearch search) {
        this.getDebugInfo();
        return login.getLoginRegsiterSt(search);
    }
}

解決辦法

接口中添加相應(yīng)的注解。

改正后的代碼：

@Component("loginRegisterService")
@Path("statistics")
@Produces({ContentType.APPLICATION_JSON_UTF_8})
public class LoginRegisterServiceImpl implements LoginRegisterService {
    Log logger = LogFactory.getLog(LoginRegisterServiceImpl.class);

    @Resource
    private LoginRegisterStRepo login;
    /**
     * 根據(jù)查詢條件查詢登錄注冊(cè)訪問(wèn)統(tǒng)計(jì)數(shù)據(jù)
     *
     * @param search
     * @return
     */
    @Override
    @GET
    @Path("login_reg")
    public List getLoginRegSt(@BeanParam final BaseSearch search) {
        this.getDebugInfo();
        return login.getLoginRegsiterSt(search);
    }
｝

3.java.io.EOFException: No content to map to Object due to end of input 錯(cuò)誤日志

當(dāng)請(qǐng)求一個(gè)rest服務(wù)api時(shí)，服務(wù)器報(bào)錯(cuò)：

java.io.EOFException: No content to map to Object due to end of input

錯(cuò)誤原因

對(duì)于service的實(shí)現(xiàn)，接收參數(shù)沒有注解為javax.ws.rs.*?類型之一，*包括：BeanParam和QueryParam,至于注解哪一種，需要根據(jù)情況而定，如果參數(shù)是Bean，用前者，是單個(gè)接收參數(shù)，用后者。

注意：這種錯(cuò)誤出現(xiàn)時(shí)整個(gè)service沒有注解，如果一個(gè)service中單個(gè)方法沒有注解，則會(huì)出現(xiàn)#2的情況。

解決辦法

加入上述相應(yīng)的注解。

/**
     * 訂單復(fù)購(gòu)率訂單數(shù)統(tǒng)計(jì)數(shù)據(jù)
     *
     * @param search
     * @return
     */
    @Override
    @GET
    @Path("reorder")
    public List> getReOrder(@BeanParam final BaseSearch search) {
        return null;
    }

4.Due to limitations of the BasicDBObject, you can’t add a second ‘$and’ 錯(cuò)誤日志

首先這是一個(gè)mongodb的錯(cuò)誤，暫且放到這里面。

java.lang.RuntimeException: org.springframework.data.mongodb.InvalidMongoDbApiUsageException: Due to limitations of the com.mongodb.BasicDBObject, you can"t add a second "$and" expression specified as "$and : [ { "time" : { "$gte" : null }}]". Criteria already contains "$and : [ { "appid" : { "$regex" : "fgdarr561puu" , "$options" : "i"}}]".

錯(cuò)誤原因

在一個(gè)Criteria實(shí)例中只能使用一次andOperator方法,而我這里使用了兩次，因?yàn)閍ppid和mobile都不為空。

if (share.getAppid() != null && StringUtils.isNotEmpty(share.getAppid())) {
                criteria.andOperator(Criteria.where("appid").regex(share.getAppid(), "i"));
if (share.getMobile() != null) {
   criteria.andOperator(Criteria.where("mobile").regex(share.getMobile(), "i"));

如果要使用過(guò)個(gè)字段的操作，請(qǐng)看mkyong的解決方法：

Problem
Using Spring data and Mongodb, below is a function to find data within a date range.
public List findByIpAndDate(String ip, Date startDate, Date endDate) {

    Query query = new Query(
        Criteria.where("ip").is(ip)
        .andOperator(Criteria.where("createdDate").gte(startDate))
        .andOperator(Criteria.where("createdDate").lt(endDate))
    );
                
    return mongoOperation.find(query, RequestAudit.class);

}
It hits following error message :
org.springframework.data.mongodb.InvalidMongoDbApiUsageException: 
    Due to limitations of the com.mongodb.BasicDBObject, you can"t add a second "$and" 
    expression specified as "$and : [ { "createdDate" : { "$lt" : { "$date" : "2013-02-25T16:00:00.000Z"}}}]". 
    Criteria already contains "$and : [ { "createdDate" : { "$gte" : { "$date" : "2013-02-24T16:00:00.000Z"}}}]"

### Solution
Adding multiple “$and” operators on the same field “createdDate” will make Spring interprets it into a wrong mongodb query. To fix it, change the query to follow :


Query query = new Query(
    Criteria.where("ip").is(ip)
    .andOperator(
        Criteria.where("createdDate").lt(endDate),
        Criteria.where("createdDate").gte(startDate)
    )
);
For multiple criteria on the same field, uses a “comma” to combine them.

解決方法

如果你的需要和mkyong的一樣，可以使使用合并字段到andOperator()方法中，當(dāng)然你可以使用and()方法，由于我這里要對(duì)參數(shù)過(guò)濾，選擇使用and()操作。
擴(kuò)展：類似的錯(cuò)誤經(jīng)常在我們判斷的時(shí)間字段上，比如我們需要做開始時(shí)間和結(jié)束時(shí)間范圍內(nèi)的操作，此時(shí)我們是不是要判斷開始時(shí)間和結(jié)束時(shí)間，如下：。

if (share.getStart() != null && share.getStart() != 0) {
    criteria.and("time").lt(share.getEnd());
}
if (share.getEnd() != null && share.getEnd() != 0) {
    criteria.and("time").gte(share.getStart());
}

這段代碼也會(huì)報(bào)錯(cuò)，Criteria不允許同一字段多次出現(xiàn)在操作（and,andOperator,etc）中。
修改上述邏輯：

if (share.getStart() != null && share.getStart() != 0 && share.getEnd() != null && share.getEnd() != 0) {
    criteria.and("time").gte(share.getStart()).lt(share.getEnd());
} else if (share.getStart() != null && share.getStart() != 0 && (share.getEnd() == null || share.getEnd() == 0)) {
    criteria.and("time").lt(share.getEnd());
} else if ((share.getStart() == null || share.getStart() == 0) && share.getEnd() != null && share.getEnd() != 0) {
    criteria.and("time").gte(share.getStart());
}

6. java.net.SocketTimeoutException: connect timed out 錯(cuò)誤日志

com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}. Client view of cluster state is {type=UNKNOWN, servers=[{address=10.132.0.169:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.SocketTimeoutException: connect timed out}}]

錯(cuò)誤原因

出現(xiàn)這類情況，大概有以下幾種情況：

mongo地址開啟了bind_ip

操作系統(tǒng)開啟了防火墻，shell可以連接，但是java程序不能連接

程序連接配置錯(cuò)誤，比如ip，port

程序本身寫法錯(cuò)誤

解決辦法

如果開啟了bind_ip，請(qǐng)加入你的服務(wù)器ip地址到該配置，或者，如果沒有必要的時(shí)候，配置成0.0.0.0，這樣任意機(jī)器均可訪問(wèn)

具體請(qǐng)看這里：centos7防火墻導(dǎo)致java程序訪問(wèn)mongodb3.0.1時(shí)報(bào)錯(cuò)的問(wèn)題

配置mongo的連接，仔細(xì)檢查ip、port的配置，有時(shí)候會(huì)把169寫成196類似的錯(cuò)誤

程序錯(cuò)誤，請(qǐng)修改bug在連接

7.Unable to create a Configuration, because no Bean Validation provider could be found. 錯(cuò)誤日志

2016-08-15 13:54:30,369 [ConsumeMessageThread_1] WARN  cn.joyven.kuaidi.mq.consumer.ImportShipHandler - Failed to invoke the method ship in the service cn.joyven.test.api.OrderService.

Last error is: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

錯(cuò)誤原因

未知

解決辦法

在stackover上看到了一個(gè)解決方案：http://stackoverflow.com/ques...
這里給出一個(gè)此類問(wèn)題的確認(rèn)方法：
在dubbo的xml配置中，直接使url配置直接訪問(wèn)dubbo服務(wù)，看是否能夠正常使用，如果能夠正常使用，則說(shuō)明就是驗(yàn)證器的問(wèn)題引起的。
一般情況我們是通過(guò)zk去注冊(cè)中心訂閱服務(wù)的，不需要url配置，但為了定位問(wèn)題，如下配置（增加url配置）：

gradle項(xiàng)目：在gradle.build中增加

compile "org.hibernate:hibernate-validator:5.2.0.Final"

maven項(xiàng)目：在pom.xml中增加


    org.hibernate
    hibernate-validator
